The present disclosure relates generally to composite plates and more particularly to a composite plate for use with equipment or an article of footwear.
This section provides background information related to the present disclosure which is not necessarily prior art.
Footwear and other athletic equipment is generally designed with an emphasis on optimizing performance without increasing the overall weight of the footwear or equipment beyond a threshold amount. For example, increasing a specific stiffness and durability of a footwear plate generally results in an increase in weight due to the additional materials required to provide the increased stiffness. Conversely, reducing the weight of the footwear generally requires reducing the materials used to form the footwear plate, thereby sacrificing the strength of the plate. In order to meet the need to increase strength and durability of footwear plates, while at the same time reducing the weight thereof, the foregoing drawbacks can be overcome using composite materials exhibiting high strength-to-weight ratios to form the footwear plate.
Generally, composite footwear plates are formed from unidirectional tapes or plates only capable of offering stiffness and load path properties that are unidirectional. While a unidirectional stiffness and load path may be suitable in one region of footwear, the same unidirectional stiffness and load path may not be suitable in other regions of the footwear. Moreover, composite footwear plates are typically formed from a substantially rigid, flat preform with a uniform thickness that is difficult to shape into a three-dimensional (e.g., non-flat) shape having a variable thickness. Accordingly, composite footwear plates are generally limited to flat surface profiles with a uniform thickness that do not conform to the surface profiles of the bottom surface of a foot. In view of the foregoing drawbacks of unidirectional tapes or plates used in the formation of composite footwear plates, such composite plates are usually only incorporated into one portion of the footwear, (e.g., one of the heel region and the forefoot region). As such, conventional footwear plates do not afford maximum support in both the heel region and the mid-foot region of the footwear and, further, cannot be tailored for the particular region of the footwear.
The drawings described herein are for illustrative purposes only of selected configurations and not all possible implementations, and are not intended to limit the scope of the present disclosure.
Corresponding reference numerals indicate corresponding parts throughout the drawings.
Example configurations will now be described more fully with reference to the accompanying drawings. Example configurations are provided so that this disclosure will be thorough, and will fully convey the scope of the disclosure to those of ordinary skill in the art. Specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of configurations of the present disclosure. It will be apparent to those of ordinary skill in the art that specific details need not be employed, that example configurations may be embodied in many different forms, and that the specific details and the example configurations should not be construed to limit the scope of the disclosure.
The terminology used herein is for the purpose of describing particular exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. Additional or alternative steps may be employed.
When an element or layer is referred to as being “on,” “engaged to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly on, engaged, connected, attached, or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
The terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections. These elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example configurations.
One aspect of the disclosure provides a method of forming an article of footwear that includes attaching a first strand portion to a flexible substrate to form a first layer on the substrate and positioning a second strand portion on the first layer to form a second layer on the first layer in a plurality of discrete regions on the substrate. The method also includes positioning a plurality of traction elements into corresponding cavities formed into a first mold surface and positioning the substrate on the first mold surface to change a shape of the substrate. The method also includes applying at least one of heat and pressure to the first strand portion, the second strand portion, the substrate, and the traction elements to conform the substrate to the shape of the first mold surface and form the traction elements into the substrate at each of the discrete regions. The method also includes incorporating the substrate into an article of footwear.
In some implementations, positioning the substrate on the first mold surface includes aligning the cavities formed into the first mold surface with the discrete regions of the substrate. Attaching the first strand portion to the flexible substrate may include attaching the first strand portion to the flexible substrate via first stitching that crosses over the first strand portion and penetrates the substrate at first attachment locations that are spaced apart from the first strand portion. Additionally or alternatively, positioning the second portion on the first layer may include attaching the first strand portion to the flexible substrate via second stitching that crosses over the second strand portion, extends through the first strand portion, and penetrates the substrate at second attachment locations disposed in the discrete regions of the substrate.
In some examples, the method also includes forming the second strand portion from a plurality of different strands of fibers each corresponding to one of the discrete regions. The method may include forming at least one of the first strand portion and the second strand portion of the same, continuous strand. The first strand portion may be formed from a first tow of fibers and/or the second strand portion may be formed from a second tow of fibers. The first and second tow of fibers each include at least one of carbon fibers, boron fibers, glass fibers, and polymeric fibers.
In some configurations, the method also includes providing the first strand portion with looped portions disposed proximate to a peripheral edge of the substrate and connecting adjacent first segments. In these configurations, the method also includes removing at least one of the looped portions that extends outside the peripheral edge of the substrate to define an outer edge of the plate. Additionally or alternatively, the method may also include providing the first layer and the second layer with segments having different densities. In some implementations, attaching the first strand portion includes applying first segments of the first strand portion to the substrate in a first shape and positioning the second strand portion includes applying second segments of the second strand portion to the first layer in a second shape different than the first shape.
In some examples, applying at least one of heat and pressure includes at least one of activating a polymeric resin incorporated into the first strand portion and the second strand portion and infusing the first strand portion, the second strand portion, and the substrate with a liquid material. In these examples, the liquid material is a thermoset material. The applying at least one of heat and pressure may include subjecting the first strand portion, the second strand portion, the substrate, and the plurality of traction elements to at least one of vacuum molding and compression molding. The method may also include forming the substrate from a thermoplastic film. In some configurations, incorporating the substrate into the article of footwear includes attaching the substrate to an upper of the article of footwear.
Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.

The upper 100 includes interior surfaces that define an interior void 102 configured to receive and secure a foot for support on the sole structure 200. Ankle opening 104 in the heel portion 16 may provide access to the interior void 102. For example, the ankle opening 104 may receive a foot to secure the foot within the void 102 and facilitate entry and removal of the foot from and to the interior void 102. In some examples, one or more fasteners 106 extend along the upper 100 to adjust a fit of the interior void 102 around the foot while concurrently accommodating entry and removal of the foot therefrom. The upper 100 may include apertures such as eyelets and/or other engagement features such as fabric or mesh loops that receive the fasteners 106. The fasteners 106 may include laces, straps, cords, hook-and-loop, or any other suitable type of fastener.
The upper 100 may include a tongue portion 110 that extends between the interior void 102 and the fasteners 106. The upper 100 may be formed from one or more materials that are stitched or adhesively bonded together to form the interior void 102. Suitable materials of the upper may include, but are not limited, textiles, foam, leather, and synthetic leather. The materials may be selected and located to impart properties of durability, air-permeability, wear-resistance, flexibility, and comfort.

The footwear plate 200 defines a longitudinal axis L that extends through the forefoot portion 12, the mid-foot portion 14, and the heel portion 16. The plate 200 attaches to the upper 100 and may impart features that a conventional outsole provides.
In some examples, one or more protruding elements 215 (e.g., cleats/traction elements) extend from the ground-engaging surface 212 in a direction away from the plate 200 and the upper 100 to provide traction with soft ground surfaces, such as grass. For instance, a cleat shaft 217 associated with each protruding element 215 may attach to the ground-engaging surface 212 of the plate 200 and extend in a direction substantially perpendicular to the longitudinal axis L of the plate 200. In another configuration, an article of footwear 10h of
In some implementations, the footwear plate 200 is substantially rigid and formed from one or more composite materials. By contrast to conventional composite plates formed from unidirectional tapes that only afford directional stiffness properties, the footwear plate 200 is formed from one or more strand portions 300 arranged in selected patterns to impart anisotropic stiffness and gradient load paths throughout the plate 200. Each strand portion 300 may refer to a tow of a plurality of fibers 350, a monofilament, yarn, or polymer pre-impregnated tows that include ribbon or strips of unidirectional tape. The present disclosure will refer to each strand portion 300 as a corresponding tow 300 of fibers 350 unless indicated otherwise. As used herein, the term “tow” refers to a bundle (i.e., plurality) of filaments (e.g., fibers 350) that may be twisted or untwisted and each tow may be designated a size associated with a number of fibers 350 the corresponding tow 300 contains. For instance, the at least one tow 300 forming the footwear plate 200 may range in size from about 1,000 fibers per bundle to about 48,000 fibers per bundle.
In some configurations, the fibers 350 associated with the at least one tow 300 include at least one of carbon fibers, boron fibers, glass fibers, and polymeric fibers. The polymeric fibers can be formed of a thermoplastic material or a thermoset material. The polymeric fibers can compositionally comprise a polyurethane, a polyamide, a polyester, a polyether, a polyurethane co-polymer, a polyamide co-polymer, a polyester co-polymer, a polyether co-polymer, and any combination thereof. The polyurethane can be a thermoplastic polyurethane (TPU). The polymeric fibers can compositionally comprise polyethylene terephthalate (PET). The polymeric fibers can compositionally comprise an aramid. The polymeric fibers can compositionally comprise poly (p-phenylene-2,6-benzobisoxazole) (PBO).
Additionally, at least a portion of the fibers 350 associated the at least one tow 300 may be formed from a first thermoplastic material. Fibers such as carbon fibers, aramid fibers, and boron fibers may provide a high modulus while glass fibers (e.g., fiberglass) and polymer fibers (e.g., synthetic fibers) provide a medium modulus.
In some examples, the density of fiber per unit area varies within a single tow 300 of fibers 350. Additionally or alternatively, the type of fibers 350 forming a corresponding tow 300 may vary across the plate 200 between the forefoot region 12 and the heel region 16 and between the lateral side 18 and the medial side 20. In doing so, the plate 200 can be designed to have a stiffness gradient based on anatomical features of the foot. For instance, a stiffness of the plate 200 may increase along the length of the plate 200 from the forefoot portion 12 to the heel portion 14. In some examples, the patterns for each tow 300 of fibers 350 provides a stiffness gradient between the lateral side 18 and the medial side 20 of the plate 200 through at least one of the portions 12, 14, 16. For instance, the stiffness of the plate 200 in the forefoot portion 12 may increase in a direction from the medial side 20 to the lateral side 18. Thus, the one or more tows 300 of fibers 350 may include paths with multiple curves to steer around voids and/or to change directions in the load path of the plate 200 to accommodate anatomical features as well as to enhance performance of the footwear 10 for its intended use. In some implementations, the plate 200 is formed by embroidering at least two tows 300 of fibers 350 in a layered configuration while being affixed to a same substrate 400 (
Generally, it is difficult to manufacture a non-flat (e.g., curved/contoured) and substantially rigid composite plate in its final state from a preform plate that is initially rigid and flat in shape. Implementations herein are directed toward an embroidered preform that affixes the one or more tows 300 of fibers 350 to the same substrate 400 or different substrates 400 and applying heat to mold the embroidered preform to form the footwear plate 200 with a desired shape and curvature. Thereafter, the plate 200 may be cured to impart structural rigidity. That is to say, both the substrate(s) 400 and each tow 300 of fibers 350 are thin and flexible to allow the embroidered preform to be positioned into a mold to form the plate 200 with a three-dimensional shape having structural rigidity. In some examples, manufacturing the plate 200 includes infusing liquid thermoplastic material into the embroidered preform (e.g., one or more tows 300 of fibers 350 affixed to the substrate 400) and using vacuum molding and/or compression molding techniques to form the plate 200. The liquid thermoplastic material may include at least one of polymerizable compositions or pre-polymer materials. Additional polymers/toughening agents (such as softer polymers, rubber, and/or block copolymers) may be added to the liquid thermoplastic material to reduce brittleness of the plate 200.
In other examples, the substrate 400, or a portion thereof, is formed from a thermoset polymeric material and/or a thermoplastic polymeric material. The thermoplastic polymeric material includes a melting point below a melting point or degradation temperature of the fibers 350 of the tows 300. Here, incorporating the thermoplastic material and/or the thermoset polymeric material into the substrate 400 may be used in addition to, or in lieu of, the liquid thermoplastic material infused into the embroidered preform to melt/infuse the embroidered preform during the vacuum molding process and/or the compression molding process. Additionally or alternatively, thermoplastic yarns may be comingled with the fibers 350 of the one or more tows 300 to assist with melting/infusing the embroidered preform during vacuum molding or compression molding. Optionally, the embroidered preform may be power coated with the thermoset and/or thermoplastic polymeric materials or injection-molding techniques may be used to overmold and/or impregnate the embroidered preform with the thermoset and/or thermoplastic polymeric materials
In some configurations, the first tow 310 of fibers 350 attaches to the substrate 400 via first stitching 314. For example, the first stitching 314 may zigzag across the first tow 310 between first attachment locations located on the substrate 400. The first stitching 314 may penetrate the substrate 400 at the first attachment locations. Here, the attachment locations may be spaced apart from the first tow 310 along the perimeter edge 402 of the substrate 400 as well as around the portions of the substrate 400 exposed within the voids 316, 318. The first stitching 314 may be formed from the same material as the substrate 400 or the first stitching 314 may be formed from a different material than the material forming the substrate 400 such that the first stitching 314 is associated with a higher melting point than the substrate 400. Providing the stitching 314 with a higher melting point than the substrate 400 allows the stitching 314 to melt after the substrate 400 when heat is applied, thereby allowing the stitching 314 to retain the first tow 310 of fibers 350 when the substrate 400 begins to melt. In some examples, the first stitching 314, or at least a portion thereof, is formed from resin.
In some examples, the first tow 310 is associated with a first shape and the second tow 320 is associated with a second shape that is different than the first shape. Similarly, the third tow 330 is associated with a third shape that may be different than the first and third shapes. Accordingly, the layers associated with at least two of the tows 310, 320, 330 may be anisotropic. Other configurations may include the first shape being approximately the same as the second shape and/or the third shape. In some implementations, at least two of the tows 310, 320, 330 have approximately the same length. By contrast, other implementations include at least two of the tows 310, 320, 330 having different lengths. For instance, the examples of
In some implementations, the second tow 320 (i.e., second strand portion) is disposed on the first layer (e.g., the first tow 310) and includes second segments 322 that each extend between two different locations along the peripheral edge 402 of the substrate 400 to form a second layer on the first layer. The second segments 322 may be convergent with the first segments 312. The first tow 310 of fibers 350 and the second tow 320 of fibers 350 may be formed from the same or different materials. For instance, the first tow 310 and/or the second tow 320 may include at least one of carbon fibers, boron fibers, glass fibers, and polymeric fibers. In some examples, the second tow 320 of fibers 350 includes approximately the same number of fibers 350 as the first tow 310 of fibers 350. In other examples, the second tow 320 of fibers 350 includes a different number of fibers 350 than the first tow 310 of fibers 350. As with the first tow 310, the second tow 320 of fibers 350 may include second looped portions 323 (
The second tow 320 of fibers 350 may attach to the substrate 400 via second stitching 324 that may zigzag across the second tow 320 between second attachment locations located on the substrate 400. In some examples, the second stitching 324 penetrates the substrate 400 at the second attachment locations. Additionally or alternatively, the second stitching 324 may extend through the first tow 310 of fibers 350. In other words, the second stitching 324 may attach the second tow 320 of fibers 350 to the substrate 400 by crossing over the second tow 320 of fibers 350, extending through the first tow 310 of fibers, and penetrating the substrate 400 at the second attachment locations.
In some scenarios, the first stitching 314 and/or the second stitching 324 is formed from resin. Additionally or alternatively, at least one of the first stitching 314 and the second stitching 324 is formed from the same material as the substrate 400. In some configurations, at least one of the first stitching 314 and the second stitching 324 has a higher melting point than the substrate 400. Here, the higher melting point allows the stitching(s) 314, 324 to melt after the substrate 400 begins to melt during thermal processing so that the corresponding tows 310, 320 are kept in place by the stitching(s) 314, 324. The stitching(s) 314, 324 may also include materials that match optional infused polymers used for compression molding and/or vacuum molding.
The third tow 330 (i.e., third strand portion) is disposed on the second layer (e.g., the second tow 320) and includes third segments 332 that each extend between two different locations along the peripheral edge 402 of the substrate 400 to form a third layer on the second layer. As with the first segments 312 of the first tow 310, the second segments 322 and the third segments 332 of the corresponding second and third tows 320, 330 may each be disposed adjacent and substantially parallel to one another.
In some configurations, the third tow 330 of fibers 350 attaches to the substrate 400 via third stitching 334 that zigzags across the third tow 330 between third attachment locations located on the substrate 400. In some examples, the third stitching 334 penetrates the substrate 400 at the third attachment locations. Additionally or alternatively, the third stitching 334 may extend through at least one of the first tow 310 of fibers 350 and the second tow 320 of fibers 350. In other words, the third stitching 334 may attach the third tow 330 of fibers 350 to the substrate 400 by crossing over the third tow 330 of fibers 350, extending through the first tow 310 and/or the second tow 320, and penetrating the substrate 400 at the third attachment locations.

The embroidered preform associated with the footwear plate 200a includes the substrate 400, a first tow 310a of fibers 350, a second tow 320a of fibers 350, and a third tow 330a of fibers arranged in a layered configuration. The tows 310a, 320a, 330a may be formed from the same continuous strand/bundle of fibers 350 or at least one of the tows 310a, 320a, 330a may be formed from a different continuous strand/bundle of fibers 350. As with the tows 310, 320, 330 of
The first tow 310a of fibers 350 includes first segments 312a that each extend between two different locations along the peripheral edge 402 of the substrate 400 to form a first layer on the substrate 400 (e.g., upon the top surface 410). The first segments 312 are disposed adjacent and substantially parallel to one another.
The second tow 320a of fibers 350 includes second segments 322a that each extend between two different locations along the peripheral edge 402 of the substrate 400 to form a second layer on the first layer. Here, the second segments 322a are convergent with the first segments 312a and disposed adjacent and substantially parallel to one another. For instance, the second segments 322a may be applied to the first layer at a second angle α2 relative to the longitudinal axis L of the substrate 400 that is different than the first angle α1. In some examples, the first layer associated with the first tow 310a and the second layer associated with the second tow 320a are anisotropic to impart gradient stiffness and gradient load paths throughout the plate 200a.
The third tow 330a of fibers 350 includes third segments 332a that each extend between two different locations along the peripheral edge 402 of the substrate 400 to form a third layer on the second layer. Here, the third segments 332a are convergent with the first segments 312a and the second segments 322a and disposed adjacent and substantially parallel to one another. For instance, the third segments 332a may be applied to the second layer at a third angle α3 relative to the longitudinal axis L of the substrate 400 that is different than the first angle α1 and the second angle α2. Other configurations may include attaching each tow 310a, 320a, 330a to a separate corresponding substrate and stacking the substrates to form a substrate stack such that the first tow 310a is disposed between a bottom substrate and an intermediate substrate, the second tow 320a is disposed between the intermediate substrate and a top substrate, and the third tow is disposed upon the top substrate.

In some examples, the raised back portion 404 and the tow 300d of fibers 350 provide a separate embroidered preform that may be subjected to pressure and/or heat to form the heel counter 204. For instance, the raised back portion 404 may include a substantially flat substrate and the segments 302d of the tow 300d may attach to the raised back portion 404 via stitching. The fibers 350 of the tow 300d may be co-mingled with thermoplastic polymer fibers and/or thermoplastic yarns and the raised back portion 404 may be formed from a thermoplastic film. The stitching may be formed from a same thermoplastic material as the thermoplastic film, but may include a higher melting point to hold the segments 302d in place as the thermoplastic film of the raised back portion 404 begins to melt. Additionally or alternatively, the embroidered preform including the tow 300d and the raised back portion 404 may be consolidated with liquid material including a thermoplastic material and/or a thermoset material to assist with affixing/bonding the tow 300d to the raised back portion 404 when pressure and heat is applied. Accordingly, the embroidered preform including the tow 300d and the raised back portion 404a may be positioned into a mold and pressure may be applied to the preform 300d, 404 by subjecting the preform 300d, 404 to at least one of compression molding and vacuum molding while enclosed within the mold to form the finished heel counter 204.
Due to the curvature requirements of the heel counter 204 having to extend around the perimeter of the heel region 16 of the footwear 10, in some examples, the heel counter 204 is formed by separately forming two separate halves. For instance, a first preform 300d, 404a may be subjected to the at least one of compression molding and vacuum molding while enclosed within the mold to form a first half of the finished counter 204, and a second preform 300d, 404 may be subjected to the at least one of compression molding and vacuum molding while enclosed within a mold to form a second half of the finished counter 204. Here, the first half may have a curvature that extends along the perimeter edge 402 of the substrate 400d in the heel region 16 from the lateral side 18 to the heel end, and the second half may have a curvature that extends along the perimeter edge 402 of the substrate 400d in the heel region 16 from the medial side 20 to the heel end. The first and second halves may be combined to form the whole heel counter 204.
The reinforcing cage 206 provides a reinforcing structure that extends away from the footwear plate 200e and that may secure to exterior surfaces of the upper 100e or may extend between the material elements forming the upper 100e in order to secure the footwear plate 200e to the upper 100e. In some examples, the reinforcing cage 206 extends around the foot in the mid-foot portion 14, for example, to provide additional support for the foot. In these examples, the reinforcing cage 206 includes a lateral portion 268 that extends around the lateral side 18 of the footwear 10e and a medial portion 262 that extends around the medial side of the footwear 10e. Distal ends of the lateral portion 268 and the medial portion 262 may extend from away from the plate 200e toward corresponding distal ends to define a gap 265 therebetween that extends along the instep of the foot corresponding to at least a portion of a throat opening defined by the upper 100e. In some implementations, a flat intermediate portion 266 connects opposing ends of the lateral portion 268 and the medial portion 262 opposite the gap 265. Here, the intermediate portion 266 may provide increased reinforcement for the reinforcing cage 206 during use of the footwear 10e.

As with the heel counter 204 of
The tow 300g of fibers 350 could be thermoformed directly to the plate 400g such that subjecting the tow 300g of fibers 350 to the thermoforming process (i.e., subjecting the tow 300g to heat and pressure) causes the tow 300g to be attached to the material forming the substrate 400g. In another configuration, the tow 300g could first be subjected to a thermoforming process and could subsequently be attached to the material forming the substrate 400g via a suitable adhesive. Regardless of how the tow 300g is attached to the material forming the substrate 400g, attaching the tow 300g to the substrate 400g increases the overall stiffness and strength of the footwear plate 200g without overly increasing the weight of the plate 200g. In short, providing the substrate 400g with fibers 350 only in discrete areas provides the plate 300g with targeted strength, as fibers are only added where increased strength and/or stiffness is needed.
In some examples, the tow 300g of fibers 350 includes looped portions 303 connecting adjacent segments 302g. The tow 300g may be formed from a continuous strand of fibers 350 that includes at least one of carbon fibers, boron fibers, glass fibers, and polymeric fibers. The first tow 300g of fibers 350 attaches to the bottom surface 412g of the substrate 400g and extends around at least a portion of the protruding members 215 (e.g., cleat members) and/or surrounds at least one of the cleat members 215. For instance, the first tow 300g may extend around cleat members 215 disposed in the forefoot portion 12 proximate to the first end 1 of the substrate 400g. In some examples, at least one of the plurality of segments 302g surrounds at least one of the cleat members 215. In some examples, at least two of the segments 302g cooperate to form at least one void 316g such that the substrate 400g (e.g., bottom surface 412g) is exposed within the at least one void 316g.
In some configurations, the tow 300g of fibers 350 wraps around the substrate 400g to provide one or more bundles 380, 381, 382, 383 of the plurality of segments 302g.

In addition to defining a shape that imparts a shape to the embroidered preform that corresponds to the ground-engaging surface 212h of the plate 200h when compressed between the mold portions 82, 84h, a contact surface 88h of the bottom mold portion 84h defines a plurality of cavities 89h that form and shape the fibers 350 of the second tow 320h into corresponding ones of the plurality of protruding elements 215h and, if present, receive the tips 217h therein. In some examples, the lower mold portion 84h is fixed and the upper mold portion 82 translates toward the lower mold portion 84h to close the mold 80h and thereby compress the embroidered preform therebetween. In other examples, the lower mold portion 84h and the upper mold portion 82 may each translate toward one another or only the lower mold portion 84h may translate toward the upper mold portion 82.

In these examples, at least one of the tows 300i is applied to the substrate in a different shape than the other tows 300i applied to the substrate. Additionally or alternatively, the each tow 300i may be formed from a same continuous, strand of fibers 350, or at least one of the tows 300i may be formed from a different strand of fibers 350 than the other tows. Moreover, a density/concentration of tows 300i may vary across the plate 200i to provide gradient stiffness properties along the plate 200i. For instance, center regions of the plates 200i may include a greater concentration of fibers 350 than perimeter regions of the plates 200i to provide increased stiffness at locations where the force of an impact is greater. For instance, at least two different tows 300i of fibers 350 may overlap in specified regions of the plates 200i to increase the concentration of fibers 350. The material(s) of the tows 300i of fibers 350 may cooperate to provide gradient stiffness and gradient load paths throughout the plate 200i.
Stitching may attach the tows 310l, 320l to the substrate 400l at corresponding attachment locations that may penetrate the substrate 400l through at least the top surface of the substrate. The first tow 310l (i.e., first strand portion) may define a plurality of first segments 312l that each extend between two different locations along the substrate 400l to form a layer thereon and define at least one void 1402 exposing the substrate 400l. In some configurations, portions of the first segments 312l that extend beyond a perimeter edge 4021 of the substrate 400l are removed to define a perimeter of the finished shin guard 1400. In some examples, looped portions of the first segments 312l that extend outside the perimeter edge 4021 are removed to eliminate the presence of pinch points when the embroidered preform plate 200l is subjected to heat and pressure. The substrate 400l may be removed within each void 1402 to provide the shin guard 1400 with the one or more voids 1402 to reduce weight. The second tow 320l of fibers 350 may operate as an inner reinforcement area surrounding the voids 1402. Here, the inner reinforcement area defined by the second tow 320l may provide additional reinforcement or structural support for the first segments 312l of the first tow 310l in regions proximate to the at least one void 1402.
