preparation example Construction

[0016] The disclosure provides a method for preparing a carbon fiber composite reinforced plate for vehicles. The preparation method includes: laying a carbon fiber braided layer and a glass fiber braided layer in superposition to obtain an inner fiber board; mixing graphene oxide and a first resin The resin is covered on the surface of the carbon fiber braided layer and the glass fiber braided layer, and the first compression molding is performed to obtain an inner layer composite board; the mixed braided layer made of aramid fiber and polyethylene fiber is covered on the said On the outer side of the inner layer composite board, the second resin and foaming agent are covered on the surface of the mixed braided layer and the inner layer composite board, and the second compression molding is performed to obtain a composite reinforced board.

[0017] According to the present disclosure, the second resin is molded together with the foaming agent, and the second resin of the obtai...

Embodiment 1

[0043] Graphene oxide (Changzhou Sixth Element Materials Technology Co., Ltd., 3-10 layers of graphene oxide) and epoxy resin particles (Huntsman) were evenly mixed and then heat-treated at 100° C. for 40 minutes to obtain a mixed resin.

[0044] Carbon fiber (Toray T700 carbon fiber in Japan) and glass fiber (Zhejiang Jushi Group Co., Ltd.) are woven into a carbon fiber braided layer and a carbon fiber braided layer of 1000 mm × 1000 mm × 0.3 mm, respectively, and then cut into 200 mm x 200 mm x 0.3 mm carbon fiber braid and carbon fiber braid.

[0045] Aramid fibers (Yantai Taihe New Materials Co., Ltd.) and polyethylene fibers (Beijing Tongyizhong Special Fiber Technology Development Co., Ltd.) were woven into a mixed weaving layer of 1000 mm × 1000 mm × 0.3 mm, and then Cut the mixed braid to 200mm x 200mm x 0.3mm.

[0046] The cut glass fiber braided layer and two carbon fiber braided layers are superimposed and laid, and the glass fiber braided layer is placed between t...

Embodiment 2

[0050] The preparation steps of Example 2 are basically the same as those of Example 1, except that graphene oxide and epoxy resin particles are not heat-treated, and are directly added to the mold for compression molding. The specific composition of the obtained composite reinforced plate is shown in Table 1 and the specific The properties are shown in Table 2.

Abstract

The invention discloses a preparation method for a carbon fiber composite reinforced board used for a vehicle, and the composite reinforced board. The preparation method comprises the following steps: subjecting a carbon fiber braid ply and a glass fiber braid ply to superposition so as to obtain an inner fiberboard; mixing graphene oxide and first resin so as to obtain mixed resin; covering the surface of the superposed carbon fiber braid ply and glass fiber braid ply with the mixed resin and carrying out primary compression molding so as to obtain an inner composite board; and covering the outer side of the inner composite board with a hybrid braid ply prepared through two-dimensional hybrid braiding of aramid fiber and polyethylene fiber, covering the surfaces of the hybrid braid ply and the inner composite board with second resin and a foaming agent and carrying out secondary compression molding so as to obtain the composite reinforced board. The composite reinforced board prepared by using the method has high strength, high modulus and good impact resistance.

Description

technical field [0001] The present disclosure relates to the technical field of automobiles, in particular to a method for preparing a carbon fiber composite reinforced plate for vehicles and the composite reinforced plate. Background technique [0002] Since the advent of carbon fiber, it has won the favor of the industry for its excellent performance. Carbon fiber has high specific strength, high specific modulus, light weight, corrosion resistance, fatigue resistance, small thermal expansion coefficient, low friction coefficient, high and low temperature resistance, but it has high brittleness, large axial force, and poor radial force , bent and easily broken. At present, carbon fiber has been widely used in construction, bridges, medical equipment, automobiles, ship parts, computers, mobile phones, luggage, sporting goods and other industries. In the automotive industry, the scope of application of carbon fiber continues to increase, and the application technology cont...
