The present disclosure relates to a method for manufacturing a long fiber composite, and to a method for manufacturing a long fiber composite in which a fiber bundle is impregnated with a resin.
Further, the present disclosure relates to a method for manufacturing a thermoplastic long fiber composite in which a fiber bundle is impregnated with a non-Newtonian resin.
Further, the present disclosure relates to a method for manufacturing a thermoplastic long fiber composite, which improves the impregnation process efficiency of the non-Newtonian resin using Equation 1 representing the correlation between the penetration pressure, effective viscosity, degree of vertical penetration, and average penetration rate of the non-Newtonian resin, and the thickness of the fiber bundle.
As the demand for high-stiffness and lightweight materials in the industrial field increases due to high oil prices, interest in continuous fiber-reinforced polymer composite materials is increasing. In the case of thermosetting resins, because of their low viscosity, the degree of impregnation of intermediate materials and finished products is excellent, and mass production is possible due to a relatively fast impregnation rate so that a lot of research and product production have been conducted in the past. However, there have been disadvantages in that recycling was difficult and the curing cycle of the resin was long. Meanwhile, as global interest in eco-friendliness increases and it is urgent to secure price competitiveness based on the global market, interest in thermoplastic polymer composite materials with advantages of recycling and shortening of process time is being more concentrated. However, in the case of a thermoplastic resin, since the melt viscosity is very high, the time required for impregnation is increased so that productivity is lowered, and due to this, it is inevitable to consider the problem of loss of price competitiveness of the product.
In thermoplastic resin polymer composite materials, the production of products using a short fiber-reinforced thermoplastic polymer composite material (Short Fiber Thermoplastic. SFT) and a long fiber-reinforced thermoplastic polymer composite material (Long Fiber Thermoplastic, LFT) has been a major part of the industry. However, the preference for continuous fiber reinforced thermoplastic polymer composite materials is increasing according to changes in the market preference that considers higher levels of high rigidity, light weight, price competitiveness, and eco-friendliness at the same time, and increasing productivity through improvement in manufacturing process efficiency thereof is emerging as a major concern.
Meanwhile, the process of attaching the resin to the fiber bundle and penetrating it to the inside of the fiber bundle is called the impregnation process, and it is extremely difficult to manufacture a resin-impregnated fiber bundle that achieves a desired manufacturing time only by attaching the resin and expecting penetration by capillary phenomenon. Accordingly, research for improving the impregnation properties that penetrate the resin into the fiber bundle is being conducted.
As a conventional art, Japanese Patent Laid-Open Publication No. Showa 60-240435 disclosed a method for manufacturing a resin-impregnated fiber bundle by maintaining all of the manufacturing apparatuses in a reduced pressure space.
It is an object of the present disclosure to provide a method for manufacturing along fiber composite in which a fiber bundle is impregnated with a resin.
Further, the present disclosure relates to a method for manufacturing a thermoplastic long fiber composite, which improves the impregnation process efficiency of the non-Newtonian resin using Equation 1 representing the correlation between the penetration pressure. effective viscosity, transverse permeability, and average penetration rate of the non-Newtonian resin, and the thickness of the fiber bundle.
In order to achieve the above object, the manufacturing method of the present disclosure,

(Vo: Average velocity of the resin penetrated into the fiber bundle, n: Power-law index of the resin, Ky: transverse permeability, μeff: Effective viscosity, ΔP: Penetration pressure of the resin into the fiber bundle, and L: Thickness of the fiber bundle).
The manufacturing method of the present disclosure can predict in advance the degree of impregnation according to processing conditions such as the type and processing form of the fiber bundle, the type of resin, etc., thereby enabling processing conditions of the fiber bundle and the resin to be set so that impregnation is completely performed within a preset time.
Further, a relatively simple process method, that is, a method of controlling the supply pressure of the resin or controlling the porosity of the fiber bundle, can improve the impregnation efficiency.

A method for manufacturing a long fiber composite according to an embodiment of the present disclosure is a method for manufacturing a long fiber composite formed by impregnating a resin in a fiber bundle, and may be a method for manufacturing a long fiber composite by impregnating the fiber bundle with a thermoplastic resin having a property of being melted particularly when heat is applied.
Accordingly, the long fiber composite according to an embodiment of the present disclosure may be a thermoplastic long fiber composite.
The term ‘fiber bundle’ in the present specification refers to a fiber bundle in which hundreds to tens of thousands of fiber units having an average diameter (Df) of several to tens of micrometers (μm) are bundled.
The fiber bundle may be at least one of glass fiber filaments, carbon fiber filaments, basalt fiber filaments, aramid fiber filaments, spectra fiber filaments, natural fiber filaments, and mixed filaments thereof.
The method for manufacturing the long fiber composite according to an embodiment of the present disclosure,
as a method for manufacturing a long fiber composite using an apparatus for manufacturing a long fiber composite, the apparatus including a container for containing a resin, a roller which is disposed inside the container and rotates in one direction, a draw-out part for applying tension to a fiber bundle and moving the fiber bundle in one direction, and a resin supply part for supplying the resin into the container,
comprises the steps of: a supply step of supplying the resin into the container at a preset pressure by the resin supply part;
a moving step of moving the fiber bundle in one direction by the draw-out part; and
an impregnation step of penetrating the resin supplied into the container into the fiber bundle, wherein the impregnation step may be controlled according to Equation 1 below.
(Vo: Average velocity of the resin penetrated into the fiber bundle, n: Power-law index of the resin, Ky: transverse permeability, μeff: Effective viscosity, ΔP: Penetration pressure of the resin into the fiber bundle, and L: Thickness of the fiber bundle).
Hereinafter, the method for manufacturing the long fiber composite according to an embodiment of the present disclosure will be described in detail for each step.
The supply step is a step of supplying the resin 100 into the container 10 at a preset pressure by the resin supply part 40.
As shown in
The resin supply part 40 may be connected to the inlet of the container 10 having a narrow inlet at the lower portion thereof as shown in
At this time, it may be preferable that the resin supply part 40 supplies the resin 100 into the container 10 at a pressure of 0.3 to 5.5 atmospheric pressure (atm).
This is for penetrating the resin 100 into the fiber bundle 200, and if the pressure is less than 0.3 atm, there may be a problem in that the resin does not penetrate into the fiber bundle, and if the pressure exceeds 5.5 atm, there may be a problem in that it is very difficult to move the fiber bundle in the penetration process of the resin.
The resin 100 may be at least one of a thermoplastic resin, a thermoplastic resin exhibiting thermoplastic properties at 50 to 500° C., a non-Newtonian resin, a power-law non-Newtonian resin showing a power-law non-Newton at room temperature, and mixtures thereof.
The resin 100 may be a non-Newtonian resin having a Power-law index of 0.25 to 0.92.
Here, non-Newtonian resin refers to a resin having a non-Newtonian property, that is, a property of changing viscosity depending on shear rate, and may be the same as non-Newtonian fluids. In the case of a Newtonian fluid, the properties or flow of the fluid are constantly maintained regardless of the external load, but the viscosity may be expressed as a function of temperature and pressure only, and such a Newtonian fluid may be a fluid having a property of maintaining a constant viscosity even when the shear rate is changed.
The non-Newtonian resin may be a power-law non-Newtonian resin.
Power-law non-Newtonian resin may mean a non-Newtonian resin in which the viscosity of the resin according to the shear rate is expressed by parameters of the Power-law index and the zero-shear rate viscosity.
Most resins such as polymer plastics exhibit shear thinning behavior, that is, a behavior in which the resin viscosity decreases as the shear rate increases. The Power-law index is an index expressed by numerically expressing the shear thinning behavior as described above, and has a value between 0 and 1. At this time, the greater the degree of decrease in resin viscosity compared to the shear rate, the closer to 0 it is, and conversely, the weaker the degree of decrease in resin viscosity compared to the shear rate, the closer to 1 it is. For example, a polypropylene resin having a severe shear thinning behavior has a Power-law index of near 0.3 to 0.4, and a polycarbonate resin having a weak shear thinning behavior has a Power-law index of near 0.9.
The non-Newtonian resin is a non-Newtonian resin that exhibits affinity with the surface of the fiber bundle, and may comprise at least one of maleic anhydride, acrylic acid, amine, ester, epoxy, and compounds to which these are chemically bonded.
Further, the non-Newtonian resin is a non-Newtonian resin showing affinity with the surface of the fiber bundle, and may include at least one of a polypropylene-based resin, a nylon-based resin, a polyethylene-based resin, a polybutylene terephthalate resin, a polyethylene terephthalate resin, a polyvinyl chloride resin, and mixed resins thereof.
The polypropylene-based resin may include at least one of homopolypropylene, propylene ethylene block copolymer polypropylene, propylene ethylene random copolymer polypropylene, and metallocene polypropylene, preferably in an amount of 40% by weight or more.
The polyethylene-based resin may include at least one of high-density polyethylene, low-density polyethylene, linear low-density polyethylene, metallocene polyethylene, and ethylene-based elastomer, preferably in an amount of 40% by weight or more.
The nylon-based resin is a resin containing an amide component, and may be at least one of nylon 6, nylon 66, nylon 12, nylon 46, polyphthalamide, amorphous nylon, and mixed resins thereof.
The moving step is a step of moving the fiber bundle 200 in one direction by the draw-out part 30.
In the method for manufacturing the long fiber composite according to an embodiment of the present disclosure, the fiber bundle 200 is moved in one direction or both directions, and the resin is penetrated into the fiber bundle.
In the fiber bundle 200, when the distance between one surface of the fiber bundle 200 and the other surface thereof is referred to as a thickness, the distance between one end and the other end of the fiber bundle in a direction perpendicular to the movement direction of the fiber bundle 200 in the above description is referred to as a width, and the distance from one end to the other end of the fiber bundle in a direction parallel to the direction in which the fiber bundle 200 moves is referred to as a length, as shown in
The draw-out part 30 may apply tension to the fiber bundle and move the fiber bundle in one direction, and the tension may be applied in a direction in which the fiber bundle is moved by the draw-out part.
The impregnation step is a step of penetrating the resin supplied into the container into the fiber bundle.
The impregnation step may be a step of filling the resin 100 in voids of the fiber bundle 200.
The fiber bundle 200 may have porosity by including voids between the plurality of fiber units. Accordingly, the fiber bundle 200 may be fibrous porous media having a plurality of voids therein, and the impregnation step may be a step in which the resin 100 penetrates into the fiber bundle and fills the voids of the fiber bundle 200.
The impregnation step may be controlled according to Equation 1 below.
(Vo: Average velocity of the resin penetrated into the fiber bundle, n: Power-law index of the resin, Ky: transverse permeability, μeff: Effective viscosity, ΔP: Penetration pressure of the resin into the fiber bundle, and L: Thickness of the fiber bundle).
Equation 1 above shows the correlation between the penetration pressure (ΔP), the effective viscosity (μeff), transverse permeability (Ky) and the average velocity of the resin penetrated into the fiber bundle (Vo) of the resin, and the thickness (L) of the fiber bundle.
At this time, the resin may preferably be thermoplastic resins having an effective viscosity, non-Newtonian resins, or non-Newtonian fluids.
The effective viscosity is a viscosity expressed by Power-law index indicating the shear thinning behavior of thermoplastic resins, non-Newtonian resins, or non-Newtonian fluids, and may be calculated by Equation 2 below.
(μo: zero-shear rate viscosity of the resin, Φmax/Φ: relative volume fraction of the fiber bundle, f(φ): fitting parameter)
The impregnation step may be controlled by the algorithm of
First, as a first step, the diameter (Df) and number of fiber units included in the fiber bundle, and the width of the fiber bundle may be set, the type of resin may be selected to set zero-shear rate viscosity (μ0) and resin's Power-law index (n), and the penetration pressure (ΔP) of the resin may be set as the processing conditions.
At this time, the diameter (Df) of the fiber units may preferably have a size of 5 to 100 μm.
If the diameter (Df) of the fiber units is less than 5 μm, there may be a problem in that the impregnation property is lowered in the step of impregnating a long fiber comprising the fiber units, and if the diameter (Df) of the fiber units exceeds 100 μm, there may be a problem in that the mechanical properties of a final product to be manufactured, that is, a long fiber composite, are deteriorated.
The width of the fiber bundle may be preferably 10 to 30 mm, more preferably 12 to 24 mm.
If the width of the fiber bundle is less than 10 mm, there may be problem in that resin impregnation is difficult, and if the width of the fiber bundle exceeds 30 mm, there may be a problem in that friction due to the speed difference between the fiber units is excessively generated.
The zero-shear rate viscosity means a viscosity of the resin at a shear rate of 0.
The resin may be a non-Newtonian resin having a zero-shear rate viscosity of 1 to 300 Pa·s.
If the zero-shear rate viscosity is less than 1 Pa·s, there may be a problem in that mechanical properties are lowered due to too low molecular weight, and if the zero-shear rate viscosity exceeds 300 Pa·s, there may be a problem in that resin impregnation is very difficult since the viscosity is too high.
Further, the resin may preferably be anon-Newtonian resin having a Power-law index of 0.25 to 0.92.
If the Power-law index is less than 0.25, there may be a problem in that it is difficult to design a polymer and an additive for improving fluidity such as a plasticizer should be excessively mixed, and if the Power-law index exceeds 0.92, there may be a problem in that permeation of the resin is very difficult.
Further, the penetration pressure (ΔP) of the resin may be preferably applying a pressure of 0.3 to 5.5 atmospheric pressure (atm).
If the penetration pressure (ΔP) of the resin is less than 0.3 atm, there may be a problem in that it is very difficult for the resin to penetrate into the fiber bundle, and if the penetration pressure (ΔP) of the resin exceeds 5.5 atm, there may be a problem in that an excessive force is applied to the fiber bundle during the resin penetration process so that movement is very difficult.
In the second step, the porosity of the fiber bundle is set under the set conditions.
The porosity may have a value of 0.1 to 0.9, but the present disclosure is not limited thereto.
The impregnation step according to an embodiment of the present disclosure may comprise a porosity control step of controlling the porosity of the fiber bundle so that a penetration time required for the resin 100 to fill the internal voids of the fiber bundle 200 becomes a preset value or less.
The porosity may be calculated by <Equation 1> below.
The porosity may have a value between 0 and 1, more preferably a value of 0.1 to 0.9.
The fiber volume fraction (Φ) occupied by the fiber units in the fiber bundle may be (1-porosity).
The porosity may vary depending on the fiber volume content, the distance between the fiber units, and the packing form of the fiber units. The long fiber composite may be manufactured at a high fiber content, and the fiber units may be packed in a hexagonal form.
Further, the distance (S) between the fiber units may be calculated by <Equation 2> below, and if the fiber units are hexagonally packed, the aspect ratio (Sf) between the fiber units may be √3.
(S: distance between the fiber units, Sf: aspect ratio between the fiber units, Φ: fiber volume fraction, Df: diameter of the fiber unit)
The number of fiber units included in the fiber bundle may be calculated by <Equation 3> below.
In the fiber bundle, through the number of fiber units included in the fiber bundle calculated by Equation 3 above and the distance (s) between the fiber units, when the fiber bundle is unfolded by fiber volume content, the number of fiber units included in one layer may be known from the unfolded width (W), and the number of fiber unit layers included in the fiber bundle may be known from the number of fiber units that are present in one layer. As such, when the number of the fiber unit layers of the fiber bundle is known, the thickness (L) through which the resin should penetrate may be known.
At this time, the penetration time may be a complete penetration time, which is a time taken to fill all the voids inside the fiber bundle or a time taken to have a porosity of the fiber bundle of 0%.
The porosity of the fiber bundle may mean a volume fraction of voids in the fiber bundle. Accordingly, when the fiber volume fraction occupied by the fiber units in the fiber bundle is ‘φ’, the porosity has a value of ‘1−φ’.
For example, if the volume content occupied by the fiber units in the fiber bundle is 40%, the fiber volume fraction may be 0.4 and the porosity may be 0.6.
When the penetration time is within 8 seconds, it may be regarded as a reference time for enabling design of the impregnation die. Accordingly, the preset time is preferably within 8 seconds, more preferably within 7 seconds, and more preferably within 6 seconds.
Here, the reference time for enabling design of the impregnation die may be a continuous manufacturing enabling time in which the fiber bundle is not uneconomical due to a slow line speed, and the stability of the resin is not hindered due to a long residence time in the die. The reference time for enabling design of the impregnation die may vary depending on the line speed of the fiber bundle and the length of the impregnation die.
In penetrating the resin into the fiber bundle, if the impregnation die is lengthened to lengthen the time the fiber bundle is in contact with the resin, it is advantageous for the impregnation, whereas there may be a problem in that a lot of force is required to move the fiber bundle. Accordingly, the penetration time may be controlled by the design of the impregnation die. Therefore, the impregnation die should be designed so that the resin may be completely impregnated into the fiber bundle within the shortest possible time. For example, if the fiber bundle moves at a line speed of 10 m/min and passes through a 1 m-long impregnation die, the resin penetration may occur while it comes into contact with the resin for about 6 seconds.
If the fiber bundle moves slower than a line speed of 10 m/min, there may be a problem in that it is disadvantageous to mass manufacturing, resulting in a decrease in manufacturing productivity, and if the length of the impregnation die becomes longer than 1 m, there may be a problem in that the load applied to the fiber bundle during movement becomes too high so that continuous manufacturing is difficult.
The porosity control step may comprise a step of controlling a distance between the respective fiber units included in the fiber bundle 200.
The step of controlling the distance between the respective fiber units included in the fiber bundle may be performed by a method of applying a force in a direction perpendicular to a direction of applying a tension to the fiber bundle.
Since the direction of applying the tension is a direction parallel to the movement direction, the direction of applying the force to the fiber bundle may be a direction perpendicular to the movement direction.
For example, the distance between a plurality of fiber units aligned in the longitudinal direction may be increased by applying a force in a direction perpendicular to the direction of applying the tension.
At this time, the amount of the resin that comes into contact with the fiber bundle may be adjusted using a resin knife 50. It is possible to control the amount of the resin that comes into contact with the fiber bundle by using the resin knife 50 so that an excessive amount of the resin does not enclose the fiber bundle at one time.
Here, the resin knife is a device for removing the resin pulled up by the rotary roller, and may be a device for adjusting the amount of the rotary roller coating resin, for example, a roll coating adjustment knife.
The apparatus for manufacturing a long fiber composite may further include a resin knife 50 positioned at the fiber bundle injection part of the first roller, and may enables the fiber units included in the unfolded fiber bundle 200 to be partially coated by adjusting the amount of the resin coated on the rotating roller 20 using the resin knife 50, that is, by adjusting the amount of the resin that penetrates into the fiber bundle. The fiber units that have been partially coated through this may be more easily separated so that the distance between the fiber units may be more easily adjusted.
The perpendicular direction in the present specification does not mean only a direction of 90° with respect to the reference direction, but may mean all of the vector components when a vector component with respect to a direction forming 90° with the reference direction exists among the vector components.
Further, the parallel direction does not mean only a direction of 0° or 180° with respect to the reference direction, but may mean all of the vector components when a vector component with respect to a direction forming 0° or 180° with respect to the reference direction exists among the vector components.
For example, the step of controlling the distance between the fiber units may be performed by a method of applying a force in a 45° or 90° direction to the direction of applying a tension to the fiber bundle, or may be performed by a method of applying a force in the thickness direction of the fiber bundle.
In the third step, after calculating the distance (S) between the respective fiber units in the fiber bundle having a specific porosity, the Average velocity (Vo) in which the resin penetrates into the fiber bundle may be calculated based on Equation 1 below, and the penetration time of the resin may be calculated therefrom.
(Vo: Average velocity of the resin penetrated into the fiber bundle, n: Power-law index of the resin, Ky: transverse permeability, μeff: Effective viscosity, ΔP: Penetration pressure of the resin into the fiber bundle, and L: Thickness of the fiber bundle).
In order to calculate the average velocity of the resin penetrated into the fiber bundle (Vo) of the fiber bundle, it is preferable to first calculate the effective viscosity (μeff) and the transverse permeability (Ky), and the effective viscosity (μeff) and the transverse permeability (Ky) may be calculated by Equations 2 and 3 below. At this time, A and B in the fitting parameters may vary depending on the packing form between the fiber units.
(μ0: zero-shear rate viscosity of the resin, Φmax/Φ: relative volume fraction of the fiber bundle, f(φ): fitting parameter, A, B: constants)
(Φmax/Φ: relative volume fraction of the fiber bundle, Df: diameter of the fiber unit, a: constant)
The effective viscosity refers to a viscosity expressed by Power-law index indicating the shear thinning behavior of thermoplastic resins, non-Newtonian resins, or non-Newtonian fluids, and the transverse permeability (Ky) refers to the degree of permeating the resin in the thickness direction of the fiber bundle 200.
The transverse permeability (Ky) of the resin may have a larger value as the porosity of the fiber bundle increases.
When the calculated penetration time exceeds a specific value in order to efficiently perform the process, the penetration time may be allowed to become a specific value or less by a method of controlling the porosity of the fiber bundle.
Accordingly, the method for manufacturing a long fiber composite according to an embodiment of the present disclosure may adjust the penetration time to a preset value or less depending on types of the resin and the fiber bundle by an easier method of controlling the porosity of the fiber bundle.
Meanwhile, in the impregnation step, the resin 100 supplied to the container 10 may pass through between a plurality of rollers 20 to penetrate into the fiber bundle 200.
At this time, the roller may include a first roller and a second roller spaced apart from each other, and the resin 100 supplied into the container 10 may pass through between the first roller and the second roller to penetrate into the fiber bundle by a preset pressure.
Further, the amount of the resin 100 penetrated into the fiber bundle 200 may be adjusted. For example, the amount of the resin penetrated by the first roller may be adjusted through the resin knife 50 positioned at the fiber bundle injection part of the first roller, through which the fiber bundle may be partially impregnated.
Further, the fiber bundle 200 may be positioned on the first roller and the second roller, and at this time, when the first roller and the second roller are rotated, the resin 100 supplied into the container 10 may be pulled up to the fiber bundle 200 located on the first roller and the second roller by the first roller and the second roller so that the resin may also be penetrated into the fiber bundle 200.
Hereinafter, the present disclosure will be described in detail through Examples and Experimental Examples.
However, Examples and Experimental Examples below are merely illustrative of the present disclosure, and the content of the present disclosure is not limited by the following Examples.
Tables 1 to 4 below are tables showing process conditions in Examples 1 to 702 below.
In order to confirm the penetration time of the resin in the method for manufacturing the long fiber composite according to the embodiment of the present disclosure, the simulation as described below was performed.
Step 1: The penetration pressure (ΔP) of the resin was set to 0.5 atm.
At this time, a polypropylene resin that was a power-law non-Newtonian resin having a zero-shear rate viscosity (μ0) of 273 Pa·s and a Power-law index (n) of 0.3 was set to be used as the resin.
Step 2: After unfolding a glass fiber bundle 200 in which several thousands of fiber units having a diameter (Df) of 20 μm were bundled to 2,400 tex to have a width of 24 mm, the unfolded glass fiber bundle 200 was set to move in a direction of the draw-out part 30.
Step 3: The distance between the fiber units was set to be adjusted so that the porosity (1-φ) of the glass fiber bundle became 0.15, and the penetration pressure was set so that the polypropylene resin was penetrated into the glass fiber bundle by applying a penetration pressure of 0.5 atm to the polypropylene resin.
