Abstract

The present invention relates to a production method for an automobile composite article with a high-performance fibre as a base material. The matching weight ratios of the materials are: 15-30% of a carbon fibre fabric, 10-20% of an ultra-strength polyethylene fibre fabric, 15-30% of a high-strength glass fibre fabric, and 40-55% of an unsaturated polyester resin or epoxy resin, wherein the three high-performance fibre fabrics used above are of 160-250 g per square metre. The high-performance fibre composite article is prepared by a vacuum-assisted forming process or an RTM forming process (a resin transfer moulding forming process). The high-performance fibre composite article prepared in the present invention has the advantages such as a low material mass, a strong bending stress resistance, a high elastic modulus, a strong impact toughness, ultraviolet resistance, a high temperature resistance, a low preparation cost etc., is mainly used for manufacturing automobile housings and parts, and is an optimum material which fulfils the energy conservation and emission reduction and lightweight equipment requirements 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. With the rapid development of science and technology, high-performance fiber composite materials have been widely used in petroleum, chemical, shipbuilding, metallurgy, mining, pressure vessel manufacturing, environmental protection, food and other industries, especially in today's new energy automobile industry, for automobile shells, etc. Components provide the best new structural materials for the lightweight development of automobiles. Such as: [0003] 1. Patent application CN102941...
