Manufacturing method of carbon fiber composite material preform for fuel cell hydrogen energy automobile

Abstract

The invention discloses a manufacturing method of a carbon fiber composite material preform for a fuel cell hydrogen energy automobile. The method specifically comprises the following steps: S1, core body glue pressing; S2, shaping of the core body; S3, graphene preparation; S4, stacking and pasting of graphene; S5, hot-pressing and curing of graphene; and S6, reinforcement of a local area. According to the manufacturing method of the carbon fiber composite material preform for the fuel cell hydrogen energy automobile, double graphene thin layers are added in the production process of the preform, and the upper limit value of pressure bearing of the preform is greatly increased without increasing the volume of the preform, so that the hardness of the preform is improved, and functional failure caused by embrittlement of the preform is avoided; and the double graphene thin layers have the heat conduction characteristic and can quickly transfer heat to implement heat dissipation during use, so that overheating of accessories caused by quick temperature rise is avoided, and the service life of the product is greatly prolonged, in other words, the safety performance is greatly improved.

Description

technical field [0001] The invention relates to the technical field of fuel cell hydrogen energy vehicles, in particular to a method for manufacturing a carbon fiber composite material prefabricated body for fuel cell hydrogen energy vehicles. Background technique [0002] Composite materials are new materials that people use advanced material preparation technology to optimize the combination of material components with different properties. The matrix materials of composite materials are divided into two categories: metal and non-metal. Commonly used metal substrates are aluminum, magnesium, copper, titanium and their alloys. Non-metallic substrates mainly include synthetic resin, rubber, ceramics, graphite, carbon, etc. Reinforcement materials mainly include glass fibers, carbon fibers, boron fibers, aramid fibers, silicon carbide fibers, asbestos fibers, and whiskers. Among them, composite materials with carbon fibers as reinforcement materials are widely used in brake ...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a method for manufacturing a carbon fiber composite material prefabricated body for fuel cell hydrogen energy vehicles, which solves the brittleness of existing composite materials that use carbon fiber as a reinforcing material in the above-mentioned background technology. The brittleness makes the brake disc or disc made of it prone to non-friction damage and functional failure, which seriously limits its life and safety and reliability.
