PREPARATION METHOD FOR HIGH-PERFORMANCE FIBRE COMPOSITE ARTICLE

摘要

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.
