[0002] Biaxially oriented carbon fiber prepreg woven fabric, also known as plain weave fabric in engineering, has a wide range of applications in many fields.

For example, the maximum length of biaxially oriented carbon fiber prepreg woven fabric that can be rolled up per roll can be determined based on the deformation. Summary of the Invention

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figure 1 As shown in the embodiment of the present invention, a method for determining the deformation of a roll-type orthogonal biaxial fabric-reinforced polymer matrix composite material may include:

[0042] S100, Obtain the deformation strain energy W of the resin R .

[0043] like Figure 2 As shown, the rolled orthogonal biaxial fabric reinforced polymer may include: a paper tube 001 and a composite material 002 rolled around the paper tube 001. The composite material 002 is composed of three layers, including: a first release film 003, a material composite 004, and a second release film 005. The material composite 004 is a base composite material. The first release film 003 and the second release film 005 are respectively attached to the upper and lower sides of the material composite 004. The first release film 003 is release paper or polyethylene film, and the second release film 005 is release paper or polyethylene film. The material composite 004 is a composite of resin and fiber, and the fiber is in the form of an orthogonal biaxial fabric.

[0044] like Figure 2 As shown, the fibers can have both warp and weft directions. Optionally, the width of the material composite 004 can be 300-1500 mm.

[0045] Among them, resin refers to an organic polymer that softens or melts when heated, tends to flow under external force when softened, and is solid or semi-solid at room temperature, and sometimes can also be liquid.

[0046] Fibers are substances composed of continuous or discontinuous fine filaments. In plants and animals, fibers play a vital role in maintaining tissue structure. Fibers have a wide range of uses; they can be woven into fine threads, yarns, and ropes, and in papermaking or felt weaving, they can be woven into fiber layers. They are also frequently used to manufacture other materials and to form composite materials with other materials.

[0047] Paper tubes are tubular objects made from paper. Most paper tubes are spiral paper tubes or seamless paper tubes.

[0048] Release paper is a type of anti-stick paper that prevents prepreg from sticking together and protects it from contamination. Release paper is made of paper coated with an anti-sticking substance, and its grades vary depending on the material, thickness, elongation, and whether it is single-sided or double-sided.

[0049] In the wet process of prepreg production, release paper is placed on both the top and bottom of the prepreg. The lower release paper adheres to the prepreg as it is wound up, so the surface of the prepreg is usually protected by a layer of release paper. The function of the release paper is to prevent the prepreg from being contaminated and to facilitate marking on its surface. Another function of the release paper is to prevent lateral cracking of the unidirectional prepreg.

[0050] Release paper should meet the following requirements: it should be able to adhere to the prepreg but be easy to separate from it; it should not chemically react with or contaminate the resin system; its length and width should remain constant when the ambient temperature and humidity change to prevent wrinkling of the release paper and the prepreg; it should have sufficient density to prevent moisture from entering the prepreg; its elongation after being stretched should be consistent with that of the fiber to prevent deformation or twisting of the prepreg due to asynchronous stretching during preparation; its thickness and mass per unit area are not easy to control precisely.

[0051] PE film, or polyethylene film, refers to film produced from PE granules. PE film is moisture-proof and has low moisture permeability. Depending on the manufacturing method and control measures, polyethylene film (PE) can be used to produce products with different properties, such as low-density, medium-density, high-density polyethylene, and cross-linked polyethylene.

[0052] Optionally, the deformation strain energy W of the resin is obtained. R ,include:

[0053] Based on formula

[0054]

[0055] Determine the deformation strain energy W of the resin R , where μ is the initial shear modulus, I1 is the strain tensor invariant, D1 is the incompressibility parameter of the resin, and J is 1.

[0056] S200, Obtain the tensile deformation energy W of the fiber under compression. F ;

[0057] Optionally, the tensile deformation energy W of the fiber under compression can be obtained. F ,include:

[0061] S300, Obtain the deformation strain energy W of the resin R and tensile deformation energy W F The modified deformation energy W generated by the interaction FR .

[0062] Understandably, since the deformation of resin and fiber affects each other, the deformation strain energy W of resin can be determined using existing deformation analysis and mechanical analysis principles. R and tensile deformation energy W F The modified deformation energy W generated by the interaction FR .

[0063] S400, the deformation strain energy W of the resin R The tensile strain energy WF and the modified strain energy W of fibers under compression FR The sum of these values ​​is used to determine the deformation of the rolled orthogonal biaxial fabric-reinforced polymer matrix composite.

[0064] The method for determining the deformation of a roll-type orthogonal diaxial fabric-reinforced polymer matrix composite material provided in this invention can obtain the deformation strain energy W of the resin. R The tensile deformation energy W of fibers under compression F And the modified deformation energy W generated by the interaction FR The deformation strain energy W of the resin R The tensile deformation energy W of fibers under compression F and corrected deformation energy W FR The sum of these values ​​is used to determine the deformation of the rolled orthogonal diaxial fabric-reinforced polymer matrix composite. Therefore, this application can determine the deformation of rolled orthogonal diaxial fabric-reinforced polymer matrix composites, which is helpful for optimizing multiple stages such as production and transportation.

[0065] The derivation process of this application is explained below:

[0066] This constitutive model is based on the theory of fiber-reinforced continuous media mechanics. It constructs a mechanical constitutive model that includes a prepreg resin matrix and reinforcing fibers. This model should be able to obtain key parameters through simple mechanical tests and perform mechanical analysis of prepreg layup materials under compression and analysis of fiber orientation changes in engineering applications.

[0067] Based on the above objectives, the fiber bed of the plain weave prepreg after resin removal is considered as a unidirectional fiber-reinforced hyperelastic matrix composite material. Based on this, a homogenization assumption is made, and its macroscopic mechanical properties can be characterized by a scalar function of the right Cauchy-Green strain tensor C and the two initial unit direction vectors a0 and b0 of the fiber, i.e., the strain energy function W = W(C, a0, b0). In this equation, C = F T F, where F is the deformation gradient tensor X and x represent the coordinates of a point mass in its initial and current states, respectively.

[0068] The deformation of plain weave prepreg under compression is decomposed into resin deformation, fiber tensile deformation under compression, and the interaction between the two. The strain energy function is decomposed as W = W(C, a0, b0) = W R +W F +W FR To make the model as simple and easy to use in engineering as possible, and considering that the deformation of the resin matrix under compression can be basically simplified to a steady shear model, therefore W R The simplest hyperelastic model, the Neo-Hookean model, is used to characterize it: It can be seen that the model is a strain energy function based on the strain tensor invariant I1. If the material is assumed to be incompressible, then J = 1. It is 0.

[0069] Based on this composite material constitutive model, code was implemented in a compression molding software written in FORTRAN, forming the core module of a composite material compression molding process simulation software with independent and controllable intellectual property rights. This software can simulate the changes in fiber orientation, deformation, wrinkling, and thickness variations of fiber preforms under pressure during the compression molding process of plain weave prepregs, filling a domestic gap in this field.
