Abstract

The invention falls into the technical field of resin material, and discloses thermoplastic resin composite material and a preparation method and application thereof. The thermoplastic resin composite material comprises 40-80 wt.% of continuous fibers, 20-30 wt.% of thermoplastic resin, 0-18 wt.% of a flame retardant, 0-9 wt.% of an anti-ultraviolet agent and 0-3 wt.% of an antioxidant. The preparation method of the thermoplastic resin composite material includes unreeling, spreading and laying fibers; impregnating unidirectional fiber fabrics; cooling and flattening; and coiling and forming. Also disclosed is a method for manufacturing an automobile door from the thermoplastic resin composite material, which includes laying impregnated unidirectional fiber tapes; molding the impregnated tapes under heating and pressing into composite sheet material; preheating the composite material; and press molding the composite material in a mold. The inventive composite automobile door has the advantages of integral molding, excellent overall properties, good impact resistance, resistance to damage, resistance to permanent deformation, etc.

Description

technical field [0001] The invention belongs to the technical field of resin materials, and in particular relates to a thermoplastic resin composite material, a preparation method and an application thereof. Background technique [0002] Thermoplastic resin composites, especially continuous fiber-reinforced thermoplastic resin composites, have many outstanding performance advantages, such as good impact resistance, easy repair after damage, long-term storage of prepregs, and recycling and reuse of products. Therefore, it has been greatly developed in recent years, and the corresponding preparation technology has also obtained great breakthroughs. However, since our country's thermoplastic composite materials are still in the initial stage of research, the variety is relatively single, and the molding process is not very mature, and the scope of application needs to be further broadened. [0003] At present, most of the doors of vehicles in our country are made of steel. Th...
