Abstract

The invention relates to a production method of a composite product which adopts high-performance fiber as a base material and is used for an automobile. The high-performance fiber comprises the following in percentage by weight: 15-30% of carbon fiber fabric, 10-20% of ultra strong polyethylene fiber fabric, 15-30% of high-strength glass fiber fabric, and 40-55% of unsaturated polyester resin or epoxy resin, the doses of the three high-performance fiber fabrics are 160-250g per square meter, respectively. The high-performance fiber composite product is prepared by a vacuum assisting molding technology or an RTM (resin transfer molding) technology. The high-performance fiber composite product has the advantages of light weight, high bending stress resistance, high elasticity modulus, high impact toughness, ultraviolet ray resistance, high-temperature resistance, low manufacturing cost, and the like, is mainly used for manufacturing automobile housing and parts, and is the optimal material suitable for energy conservation and emission reduction, and light weight equipment of new energy automobiles at present.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a production method of a composite material product for automobiles with high-performance fiber as the base material. Background technique [0002] High-performance fiber-reinforced composite material (such as carbon fiber composite material) is a new type of material; it has the advantages of light material, high strength, high modulus, strong corrosion resistance, and good impact toughness.
