Manufacturing method of carbon fiber product for fuel cell hydrogen energy automobile

Abstract

The invention discloses a manufacturing method of a carbon fiber product for a fuel cell hydrogen energy automobile. The manufacturing method comprises the following steps: S1, precursor pretreatment; S2, heating and curing; S3, plastic coating; and S4, carbon fiber yarn weaving. According to the manufacturing method of the carbon fiber product for the fuel cell hydrogen energy automobile, a layer of plastic is additionally arranged on the surface of the carbon fiber in a plastic coating process, the situation that the performance of the carbon fiber is reduced can be effectively avoided, and therefore it is guaranteed that the performance of the carbon fiber is not affected; According to the method, in a carbon fiber weaving process, the carbon fibers are combined into the plied yarn and woven into fabric, a carbon fiber forming process can be simple by adopting a weaving forming method, and manufacturing of the carbon fiber product is facilitated.

Description

technical field [0001] The invention relates to the technical field of fuel cell hydrogen energy vehicles, in particular to a method for manufacturing carbon fiber products for fuel cell hydrogen energy vehicles. Background technique [0002] Carbon fiber is mostly used in fuel cell hydrogen energy vehicles. Carbon fiber is a new fiber material with high strength and high modulus with a carbon content of more than 95%. Carbon fiber is lighter than metal aluminum, but its strength is higher than steel, and It has the characteristics of high hardness, high strength, light weight, high chemical resistance and high temperature resistance. Carbon fiber has the inherent intrinsic characteristics of carbon materials and the softness and processability of textile fibers. It is a new generation of reinforcing fibers, which also makes it very popular in aerospace, civil engineering, military, racing and other competitive sports products. [0003] In the existing manufacturing method ...

Problems solved by technology

[0003] In the existing manufacturing method of carbon fiber products for fuel cell hydrogen energy vehicles, carbon fiber silk will go through the process of winding, unwinding, weaving and other processes after production. Carbon fiber silk is worn and broken, resulting in performance degradation. Seriously, the greater the loss of strength, for this reason, we propose a method for manufacturing carbon fiber products for fuel cell hydrogen vehicles
