Abstract

The invention is applicable to the technical field of composite materials, and provides a preparation method of a carbon fiber composite material and the carbon fiber composite material, wherein the preparation method of the carbon fiber composite material comprises the following steps: kneading hollow glass bead powder, epoxy resin, a microfiber material and a coupling agent to obtain a filling material; and putting the filling material into a mold, and carrying out pressure thermal forming treatment to obtain the carbon fiber composite material. According to the preparation method of the carbon fiber composite material provided by the embodiment of the invention, the hollow glass bead powder, the epoxy resin, the microfiber material and the coupling agent are used as raw materials, so that the prepared carbon fiber composite material is light in specific gravity, is not easy to thermally deform during heating and pressurizing, does not generate a secondary foaming phenomenon, and canbe used as materials of carbon fiber bicycles, badminton rackets, soles and the like.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a method for preparing a carbon fiber composite material and the carbon fiber composite material. Background technique [0002] Composite materials need to use filling materials when they are thermoset by film pressure. The existing polyurethane foam foaming filling uses polyurethane and other filling materials, which are compressed and lose internal pressure, resulting in low strength of the produced sheet, high defect rate of product appearance depression, and second foaming after molding, resulting in product scrapping. With the development of various material technologies, composite materials are molded in a rapid curing method. Although it has the advantages of high production efficiency and low energy consumption, it is prone to secondary foaming when using current polyurethane and other filling materials, resulting in product scrapping. The rate is...

AI Technical Summary

Problems solved by technology

Existing polyurethane foam foam filling is compressed and lacks internal pressure when polyurethane and other filling materials are used, resulting in low strength of the produced sheet, dents in the appearance of the product, and a high defect rate. Second foaming occurs after molding and the product is scrapped

With the development of various material technologies, composite materials are molded in a rapid curing method. Although it has the advantages of high production efficiency and low energy consumption, it is prone to secondary foaming when using current polyurethane and other filling materials, resulting in product scrapping. The rate is high, and the rapid prototyping process cannot be popularized

[0003] In addition, in the prior art, when the carbon fiber is hardened and formed, the filling material cannot effectively support the carbon fiber, resulting in insufficient internal pressure of the forming mold, which in turn leads to a decrease in the interlayer force between the carbon fiber filaments and a decrease in strength.
