DETAILED DESCRIPTION

Three-dimensional articles may be used to enhance the appearance, structure, and/or function of vehicles including, but not limited to, recreational vehicles, motorcycles, automobiles, trucks, boats, and airplanes. In some embodiments, the three-dimensional article may be a decorative article. The three-dimensional article may be a sandwiched article (e.g., a cured sandwiched article). In certain embodiments, a sandwiched article may include a core positioned between two or more outer layers. A sandwiched article may be cured and then connected (e.g., adhered) to a vehicle or to a portion of a vehicle (e.g., a surface of a vehicle or a surface of a portion of a vehicle) and finished as desired. Adhering a sandwiched article to a surface of a vehicle may include providing an adhesive or other substance to a portion (e.g., a back layer) of the sandwiched article. As used herein, “substance” may generally refer to material from which something is made or which has discrete existence. For example, a substance may be a composition that may be spread on a surface or a piece of a material that can be placed on a surface. As used herein, “providing” generally means to supply or make available to (e.g., to supply adhesive to a sandwiched article with any application process, method, or tools known in the art). A cured sandwiched article connected to a vehicle may appear as a seamless, raised contour on the vehicle.

FIG. 1A depicts a perspective view of an embodiment of sandwiched article 100 that may be used for enhancement of a vehicle. Sandwiched article 100 may be a regular or irregular article of constant or varying thickness. Sandwiched article 100 may have tapered edges to allow for a seamless look following adhesion of the sandwiched article to a vehicle. In some embodiments, as depicted in FIG. 1B, top surface 102 of sandwiched article 100 is contoured while bottom surface 104 is substantially flat. In certain embodiments, top surface 102 and bottom surface 104 of sandwiched article 100 are both contoured. For example, top surface 102 may be contoured to achieve a desired visual or structural effect, while bottom surface 104 is contoured to conform to a portion of the vehicle to which sandwiched article 100 is to be connected. FIG. 2 depicts a perspective view of an embodiment of sandwiched article 100 with contoured top surface 102 and contoured bottom surface 104.

FIG. 3 depicts a cross-sectional view of an embodiment of sandwiched article 100. Sandwiched article 100 may include core 106 between one or more backing layers 108 and one or more top layers 110. Core 106 may include one or more pieces of one or more materials, such as rubber, wood, plastic, clay (e.g., curable clay), polymer foams (e.g., polyurethane foam), etc. In some embodiments, core 106 may be substantially rigid (e.g., inflexible). In certain embodiments, at least a portion of core 106 may be somewhat flexible or malleable.

In some embodiments, backing layers 108 and top layers 110 may be woven or nonwoven, flexible, and/or permeable. Backing layers 108 and top layers 110 may include fiberglass and/or natural and/or synthetic fibers. For example, backing layers 108 and top layers 110 may include fiberglass mats, chopped fiberglass strand mats, random layers of fiberglass, fiberglass fabric, cut glass fibers, ground glass fibers, mineral fibers, natural fiber mats, natural knitted fabrics, cut natural fibers, cut natural fiber mats, non-woven fabrics based on polymer, carbon or aramid fibers, and knitted fabrics based on polymer, carbon or aramid fibers. Backing layers 108 and top layers 110 of the sandwiched article may be the same or different. In some embodiments, backing layers 108 and top layers 110 may be different weights and/or thicknesses of a similar composition and/or construction. In certain embodiments, fiber-optic fibers or strands may be provided on the outermost top layer and/or between two layers (e.g., positioned or sandwiched between two top layers or underneath a final clear coat) to enhance a sandwiched article with lighting effects.

As depicted in FIG. 3, sandwiched article 100 may include one backing layer 108. Backing layer 108 may be made of, for example, fiberglass (e.g., a heavy fiberglass sheet or mat) or KEVLAR® (e.g., woven KEVLAR® fabric). A relatively heavy backing layer 108 (or combination of backing layers) may provide structural support for sandwiched article 100. In some embodiments, a relatively heavy backing layer may include fiberglass fabric with a weight of at least 4 ounces per square yard (e.g., 4, 10, or 38 ounces per square yard). In certain embodiments, a texture and/or composition of backing layer 108 may be chosen to enhance adhesion of sandwiched article 100 to a surface of a vehicle.

In some embodiments, sandwiched article 100 may include one or more (e.g., two, three, four, or more) top layers. In certain embodiments, top layers 110, 110′, and 110″ may be of substantially the same composition, construction, and/or weight. For example, top layers 110, 110′, and 110″ may be woven fiberglass fabric of substantially the same mesh. In some embodiments, top layer 110′″ may be a different composition and/or weight than one or more of top layers 110, 110′, and 110″. For example, top layer 110′″ may be a finer mesh woven fiberglass material than any of top layers 110, 110′, and 110″. In certain embodiments, sandwiched article 100 may include two or more top layers 110 of successively finer mesh woven fiberglass material. Having finer mesh top layers 110 may advantageously allow for a smoother finish of top surface 102 of sandwiched article 100. In some embodiments, a texture of top layer 110 may be chosen to impart a desired texture to top surface 102 of sandwiched article 100.

Backing layers 108 and top layers 110 may be adhered to each other and/or to core 106 with one or more curable substances. The curable substance may include, but is not limited to, polyurethane resin, acrylic, methacrylics, polyesters, etc. The curable substance may be cured in any manner generally known in the art including curing with, but not limited to, heat, light, and/or other forms of electromagnetic radiation.

In some embodiments, a sandwiched article may be formed and then cured to conform to a portion of a vehicle and later adhered to the same portion of the vehicle. In certain embodiments, a sandwiched article may be formed and then cured to conform to a portion of a vehicle and then later adhered to a substantially similar portion of another vehicle. In other embodiments, a sandwiched article may be formed, cured to conform to a model of a portion of a vehicle, and then later adhered to a vehicle with a contour substantially similar to the model to which the sandwiched article was conformed.

In some embodiments, a sandwiched article may be a custom (e.g., one of a kind) design. A custom design may be constructed and cured to conform as desired to a selected portion of a vehicle. A custom design may include decorative features as chosen by a purchaser of the design. In some embodiments, a sandwiched article may include a company name, logo, emblem, or design chosen for advertising purposes. In certain embodiments, a sandwiched article may be a standard design that is made to fit a commercially available product. For example, a quantity of substantially similar sandwiched articles may be produced for enhancement of a portion of a widely available motor vehicle, such as a gasoline tank for a motorcycle of a popular make and/or model. Enhancing a motorcycle gasoline tank with a sandwiched design may advantageously allow the gasoline tank to be embellished nondestructively (e.g., providing an ornamental exterior without heating, impacting, denting, or otherwise deforming the gasoline tank) such that properties such as shape and/or strength of the gasoline tank are not altered.

For custom and/or commercially available sandwiched articles, cores may be shaped as desired by methods including, but not limited to, molding, cutting, sculpting, and/or combinations thereof. A desired shape may include, but is not limited to, a regular or irregular shape of constant or varying thickness. In some embodiments, a desired shape may be a pattern that is drawn or printed on paper or other surface or transferred to a piece of core material. The core material may be of any dimension (e.g., size, shape, thickness) required for a desired three-dimensional article. In certain embodiments, core material may be cut into a desired shape by methods known in the art, including manually or mechanically forcing a hot wire through the core material to cut the core material in the desired shape. FIG. 4 depicts a perspective view of an embodiment of core 106 that has been cut from a piece of core material.

In some embodiments, a cut or formed core may be finished by methods including, but not limited to, trimming, sculpting, sanding, and/or combinations thereof. Finishing a core may include detailing such as, for example, rounding edges, smoothing corners, tapering sides, and forming grooves and/or ridges. In certain embodiments, a top and/or sides of a core may be finished, while a bottom of the article may be left substantially unchanged. For example, if the core is cut from a rectangular solid, the bottom of the core may be left substantially flat. FIG. 5 depicts core 106 from FIG. 4 after finishing (e.g., contouring) of the top and sides of the core.

Before and/or after a core has been formed and/or finished, at least a portion of the core may be altered to allow for bending of the core. Bending of the core may advantageously allow the core to be conformed to a contour of the object (or a substantially similar object) to which the core is to be adhered. In some embodiments, altering the core may include, for example, cutting and/or notching a portion of the core (e.g., cutting partially through the core from a first side toward a second side) with any cutting means known in the art. Cutting of a portion of the core may assume a regular pattern or may include one or more irregular cuts. Cutting of a portion of the core may include making cuts of fixed or variable length to a fixed or variable depth.

One or more sides of a core may be altered to allow for bending of the core. For example, a top surface and/or a bottom surface of a core may be altered to allow for bending of the core. Altering a top surface of a core (e.g., cutting partially through the core from the top toward the bottom) may allow at least a portion of the core to be bent to conform to a convex contour of a portion of a vehicle. Altering a bottom surface of a core (e.g., cutting partially through the core from the bottom toward the top) may allow at least a portion of the core to be bent to conform to a concave contour of a portion of a vehicle. In some embodiments, a top surface and a bottom surface of a core may be altered to allow the core to conform to convex and concave contours of a portion of a vehicle. In some embodiments, one or more side portions of a core may be altered to allow for lateral bending of the core. FIG. 6 depicts core 106 of FIG. 5 with cuts 112 on top of the core to allow the core to be conformed to a convex contour of a portion of a vehicle.

After a core has been formed as desired, the core may be sandwiched between two or more layers to form a sandwiched article. In some embodiments, the sandwiched article may include a backing layer and one or more top layers. In certain embodiments, the sandwiched article may include two or more backing layers and two or more top layers. For example, a sandwiched article may include a backing layer and two to four top layers.

In some embodiments, a sandwiched article may be formed on an anti-stick surface. As used herein, “anti-stick” generally means any surface chosen to inhibit sticking of portions of the sandwiched article (e.g., a backing layer, a top layer that overlaps the backing layer) to the surface while the sandwiched article is being formed. An anti-stick surface may include, but is not limited to, a layer of plastic or a perhalogenated (e.g., perfluorinated) surface or layer. In certain embodiments, an anti-stick surface may act as an impermeable barrier between the sandwiched article and the work surface below the sandwiched article.

A backing layer may be placed on the anti-stick surface. Dimensions of a backing layer may be chosen to be larger than dimensions of the bottom surface of the core. That is, the backing layer may be chosen (e.g., cut) such that the core, when placed on the backing layer, does not contact the anti-stick surface. In some embodiments, a shape of a backing layer may be chosen to be similar to a shape of the core. After the backing layer has been placed on the anti-stick surface, a curable substance may be provided to the backing layer. The curable substance may be mixed before application. Providing the curable substance to the backing layer may include providing (e.g., applying by painting or coating) an excess amount of the curable substance on the backing layer. Applying an excess amount of the curable substance may include applying the curable substance until the backing layer no longer absorbs the curable substance or until the backing layer is saturated with the curable substance. In some embodiments, one or more additional backing layers may be placed on top of the first backing layer. In certain embodiments, a curable substance may be provided to one or more of the additional backing layers.

A core may be placed on the backing layer. FIG. 7 depicts an embodiment of core 106 on backing layer 108. Backing layer 108 is shown on top of anti-stick surface 114. In some embodiments, pressure may be applied manually or mechanically to core 106 to increase contact between backing layer 108 and the core. Increasing contact between backing layer 108 and core 106 may allow the backing layer to substantially conform to the bottom surface of the core. Applying pressure to core 106 may reduce a number and/or size of air pockets between the core and backing layer 108.

With core 106 on backing layer 108, top layer 110 may be positioned on the top surface of the core. FIG. 8 depicts an embodiment of top layer 110 on the top surface of core 106 shown in FIG. 7. In some embodiments, top layer 110 may include a woven fiberglass material with a weight of, for example, 4 ounces or less per square yard. As depicted in FIG. 9, curable substance 116 may be provided to top layer 110. Top layer 110 may be conformed (e.g., manually or mechanically) to the top surface and/or the sides of core 106 to promote contact of the core and the first top layer. Conforming top layer 110 to the top surface of core 106 may reduce a number and/or size of air pockets between the core and the first top layer. In some embodiments, conforming top layer 110 to the core may include pressing portions of the top layer that extend beyond the core onto portions of backing layer 108 that extend beyond the bottom surface of the core, thus enclosing (e.g., sealing) the core between the backing layer and the top layer.

After a first top layer has been positioned on the core, one or more additional top layers may be similarly positioned on the first top layer. In some embodiments, one or more additional top layers may include two to four (e.g., three) additional top layers. A curable substance may be applied to one or more of the additional top layers, and one or more of the additional top layers may be conformed to the core and the backing layer and/or other top layers to form a sandwiched article. In some embodiments, the first top layer and the one or more additional top layers may be of the same composition, construction, and/or weight. In certain embodiments, the first top layer and the one or more additional top layers may be of different composition, construction, and/or weight. For example, the first top layer and the one or more additional top layers may include materials such as, but not limited to, fiberglass, carbon fiber, biaxial composites, DYNEL™ fibers, etc. In some embodiments, one of the additional top layers may be a finer mesh and/or lighter weight than the first top layer. For example, the first top layer may be a woven fiberglass mesh with a weight of 4 ounces per square yard. The final top layer may be a woven fiberglass mesh with a weight of, for example, 2 ounces or 1.4 ounces per square yard. A finer fiberglass mesh may advantageously result in a finer, smoother top surface of the finished sandwiched article. In certain embodiments, for example, two additional top layers substantially the same as the first top layer may be placed on the first top layer. A third additional layer of a finer mesh may be placed on top of the second additional layer. In some embodiments, each successive additional top layer may be a finer mesh and/or lighter weight than the first top layer.

After a sandwiched article has been formed, an additional layer (e.g., a “peel” layer) may be placed on top of the sandwiched article. A peel layer may be of any composition such that the curable substance used in forming the sandwiched article does not adhere to the peel layer. In some embodiments, a peel layer may be a woven fabric made of, for example, any of the fibers previously mentioned herein. In some embodiments, a peel layer may be a tightly woven nylon fabric. In certain embodiments, a peel layer may include strips of the same or different material. As depicted in FIG. 10, strips 118 may be applied to a sandwiched article in an overlapping manner such that peel layer 120 covers a top surface of the sandwiched article. Pressure may be applied manually or mechanically to peel layer 120 to conform the peel layer to contours of the sandwiched article.

A sandwiched article may be cured to conform to a portion of vehicle and then removed from the portion of the vehicle. After removal of the cured sandwiched article from the portion of the vehicle, the cured sandwiched article may be connected to the portion of the vehicle or to a similar portion of another vehicle such that the contours of the cured sandwiched article conform to the contours of the vehicle. Thus, sandwiched articles may be manufactured in one location to conform to contours of a particular make and/or model of a vehicle and then shipped to another location to provide custom enhancements of vehicles of the same make and/or model. In some embodiments, a portion of a vehicle (e.g., a gasoline tank for a motorcycle) may be uncoupled from the vehicle, and a sandwiched article may be customized to conform to the portion of the vehicle and then adhered to the portion of the vehicle. After enhancement of the portion of the vehicle with the sandwiched article, the portion of the vehicle may be recoupled to the vehicle.

Before a sandwiched article is cured to conform to a portion of a vehicle, the portion of the vehicle may be prepared to facilitate separation of the sandwiched article from the portion of the vehicle after curing. In some embodiments, preparing the portion of the vehicle may include treating a surface of the portion of the vehicle. In certain embodiments, treating a surface of the portion of the vehicle may include providing an anti-stick coating or layer to the surface of the portion of the vehicle. An anti-stick coating or layer may be removably or irremovably provided to a portion of a vehicle. In some embodiments, an anti-stick coating may be provided to a portion of a vehicle. In certain embodiments, an anti-stick layer may be removably coupled to a portion of a vehicle. For example, metal foil (e.g., gold foil, aluminum foil) may be used as an anti-stick layer. Manual or mechanical pressure may be used to conform the layer of metal foil to a contour of the portion of the vehicle. FIG. 11 depicts a perspective view of an embodiment of vehicle portion 122, shown here as a gasoline tank of a motorcycle, during application of anti-stick layer 124. Anti-stick layer 124 may be advantageously applied smoothly to vehicle portion 122 such that the anti-stick layer is substantially smooth (e.g., without wrinkles).

A sandwiched article may be positioned as desired on at least a prepared portion of a vehicle. The sandwiched article, along with the peel layer, may be conformed to the portion of the vehicle in a desired position. In some embodiments, the surface on which the sandwiched article was formed may be transferred to the portion of the vehicle along with the sandwiched article. In certain embodiments, pressure may be applied manually or mechanically to the sandwiched article to promote contact of and/or reduce a number and/or size of air pockets between the backing layer of the sandwiched article and an anti-stick coating or layer on the portion of the vehicle. In some embodiments, a peel layer may be applied to a sandwiched article after the sandwiched article has been conformed to a portion of a vehicle. After the sandwiched article has been positioned as desired, in some embodiments, the peel layer may be covered with a first permeable layer (e.g., perforated plastic sheeting or perforated plastic bag).

In some embodiments, a first permeable layer may be covered with one or more additional permeable layers. For example, a first permeable layer may be covered with a second permeable layer. The second permeable layer may be, for example, cotton cloth or lightweight felt. In some embodiments, at least one of the additional permeable layers may help keep the first permeable layer in place. In certain embodiments, the second permeable layer may help absorb liquid (e.g., resin) applied to the sandwiched article. For example, excess resin applied to the sandwiched article may pass through openings in the first permeable layer to the second permeable layer, resulting in a smoother surface following removal of the permeable layers. FIG. 12 depicts a perspective view of an embodiment of sandwiched article 100 positioned on vehicle portion 122, with permeable layers 126, 126′ on peel layer 120.

With one or more permeable layers 126 positioned as desired on peel layer 120, vehicle portion 122 with sandwiched article 100 and backing and top layers may be sealed in a flexible, substantially impermeable enclosure (e.g., a plastic bag or a plastic layer sealed to the vehicle portion). In some embodiments, second permeable layer 126′ (or any top permeable layer) may inhibit adhesion of curable substance to the impermeable enclosure. FIG. 13 depicts a perspective view of vehicle portion 122 with sandwiched article 100 covered with permeable layers 126, 126′ in enclosure 128.

Enclosure 128 may be subjected to any process generally known in the art (e.g., a vacuum bagging process) to remove air from the enclosure. As air is removed from enclosure 128, permeable layers 126 and sandwiched article 100 may be effectively compressed toward vehicle portion 122. Compressing permeable layers 126 and sandwiched article 100 toward vehicle portion 122 may promote conforming of the sandwiched article to a contour of the object. Compressing permeable layers 126 and sandwiched article 100 toward vehicle portion 122 may compress the top layer(s) to the core and the core to the backing layer(s) to form a more stable, compact sandwiched article. In some embodiments, a vehicle portion with a sandwiched article covered with permeable layers may be placed in a vacuum chamber and the chamber may be evacuated.

Following a process designed to conform sandwiched article 100 to vehicle portion 122 and compress backing and/or top layers toward the core, enclosure 128 and the contents of the airtight compartment may be subjected to a curing process to cure the curable substance in sandwiched article 100. In some embodiments, enclosure 128 and contents of the enclosure may be subjected to heat and/or light suitable to cure curable substance in sandwiched article 100. In certain embodiments, other curing processes known in the art or combinations of such curing processes may be used to cure the one or more curable substances in sandwiched article 100.

After the curable substance in sandwiched article 100 has been cured, enclosure 128 may be opened. Permeable layers 126, 126′ (e.g., perforated plastic and felt) may be removed from peel layer 120 or sandwiched article 100. In some embodiments, peel layer 120 may be removed from sandwiched article 100 following removal of permeable layers 126, 126′. The composition and order of permeable layers 126, 126′ and the composition and application of peel layer 120 may be chosen to allow removal of the permeable layers and the peel layer without altering the top layer(s) and/or the core of sandwiched article 100. After curing, sandwiched article 100 may be removed from vehicle portion 122. FIG. 14 depicts a perspective view of cured sandwiched article 100 depicted in FIG. 13 (with backing layer 108 and top layer 110) after separation of the sandwiched article from vehicle portion 122.

A large sandwiched article may be more difficult to assemble and/or handle than a small sandwiched article. Curing a large sandwiched article may require larger, more expensive equipment and/or a longer time than curing a small sandwiched article. In some embodiments, two or more cured sandwiched articles may be pieced together on a surface of a vehicle to form a larger cured sandwiched article. For example, portions of a flame may be assembled and cured separately and then connected to a surface of a vehicle and finished to form a substantially continuous enhancement on the surface of the vehicle. Forming a cured sandwiched article from two or more pieces may advantageously allow the cured sandwiched article to be formed more quickly and/or more cost effectively.

After separation of cured sandwiched article 100 from vehicle portion 122, the sandwiched article may be finished. In some embodiments, finishing may include, but is not limited to, trimming of excess material from layers extending beyond the core, sanding sandwiched article 100 to smooth/remove rough portions, and/or sculpturing at least a portion of the sandwiched article. Edges of sandwiched article 100 may be finished to form a smooth interface between the sandwiched article and the portion of the vehicle to which the sandwiched article is to be connected. In certain embodiments, finishing may include removing loose particulate matter from cured sandwiched article 100. For example, loose particulate matter may be removed from cured sandwiched article 100 by vacuuming. FIG. 15 depicts a perspective view of an embodiment of cured sandwiched article 100 shown in FIG. 14 after finishing of the sandwiched article.

After curing and finishing, sandwiched article 100 may be connected to vehicle portion 122. In some embodiments, sandwiched article 100 may have been conformed to vehicle portion 122 during curing. In certain embodiments, sandwiched article 100 may have been conformed to a portion of another vehicle or a model of a portion of a vehicle during curing. For example, a portion of the vehicle to which sandwiched article 100 is connected may be substantially similar to a portion of the vehicle (or model of the portion of the vehicle) to which the sandwiched article was conformed during curing.

Adhering sandwiched article 100 to vehicle portion 122 may include providing adhesive (e.g., Z-1 putty, available from Joybond Co., Ltd., Tokyo, Japan), putties (e.g., ready-to-use putties) epoxy glues, two-part adhesives, two-part putties, etc. to the backing layer of the sandwiched article and/or to a surface of the portion of the vehicle before positioning the sandwiched article on the portion of the vehicle. Adhesive provided to the backing layer is desirably light, workable, durable, sandable, non-shrinking, non-swelling, and clean (e.g., low dusting, low emission). Applying adhesive to the backing layer of sandwiched article 100 provides a relatively large surface over which adhesion may occur. Application of adhesive to substantially the entire surface area of a backing layer of sandwiched article 100 may allow more secure adhesion of the sandwiched article than application of adhesive to a smaller surface area (e.g., the edges) of the sandwiched article.

In some embodiments, a surface of vehicle portion 122 may be prepared for adhesion of sandwiched article 100. Preparing a surface of vehicle portion 122 for adhesion of sandwiched article 100 may include, but is not limited to, texturing, coating, sanding, and/or combinations thereof. After adhesion of sandwiched article 100 to vehicle portion 122, the adhesive may be cured by any means known in the art (e.g., with light or heat). Curing of the adhesive may adhere the sandwiched article to the object. In some embodiments, an object may be heated, for example, to 120° F. for about 30 minutes. FIG. 16 depicts a perspective view of an embodiment of sandwiched article 100 depicted in FIG. 15 after the sandwiched article has been adhered to vehicle portion 122.

Following curing of the adhesive, curable substance 130 (e.g., putty, such as Z-1putty) may be applied to the interface between the sandwiched article and the portion of the vehicle to fill spaces between the sandwiched article and the portion of the vehicle. FIG. 17 depicts a perspective view of an embodiment of sandwiched article 100 adhered to vehicle portion 122 as depicted in FIG. 16 after smoothing of curable substance 130 around the edges of sandwiched article 100. In some embodiments, curable substance 130 may be applied to at least a portion of a top surface and/or sides of sandwiched article 100 to create a desired contour and/or texture. The curable substance may be cured (e.g., heated), and the cured substance may be finished (e.g., sanded). The curable substance may be a substance that does not change substantially in volume during heating (e.g., a “nonshrink” substance). Finishing of the cured substance (e.g., at the interface between the sandwiched article and the portion of the vehicle) may produce a smooth, seamless appearance of the sandwiched article on the vehicle.

The enhanced portion of the vehicle (i.e., the object enhanced with the sandwiched article) may be finished as desired by one or more processes including, but not limited to, priming and painting. FIG. 18 depicts a perspective view of an embodiment of sandwiched article 100 adhered to vehicle portion 122 depicted in FIG. 17, following finishing of the vehicle portion and the sandwiched article.

FIG. 19 depicts a perspective view of the embodiment of sandwiched article 100 shown in FIG. 18 with fiber-optic fibers 132 positioned between top layers 110 of the sandwiched article. Fiber-optic fibers 132 may be made of transparent materials including, but not limited to, glass, plastic, and combinations thereof. Fiber-optic fibers 132 may be positioned singly or in bundles between top layers 110. Light source 134 may be coupled to fiber-optic fibers 132. Power source 136 may be coupled to light source 134. In some embodiments, power source 136 may be a battery. In certain embodiments, light source 134 may be coupled to a power source of the vehicle rather than power source 136. Switch 138 may be positioned between the power source and the light source 134 to allow a user to enable or disable the light source as desired.
