Problems solved by technology

[0002] Fiber-reinforced thermoplastic resin composite materials, such as the technologies disclosed in US5240974 and EP0491043 patents, generally use metal fibers, carbon fibers, and glass fibers as reinforcing materials, but in some fields, such as aviation, aerospace, meteorology, etc., their strength is still relatively low , the weight is not light enough, and these reinforced materials have poor affinity with thermoplastic resins, so the relevant departments hope to provide a fiber-reinforced thermoplastic resin composite material with superior performance

Embodiment 1

[0021] 800 parts of polypropylene resin powder, 200 parts of PCS continuous high-strength polyester fibers, and 50 parts of polypropylene maleic anhydride grafts are made into prepregs by electrostatic adsorption powder impregnation method, and passed through an oven at a temperature of 195 ° C. Heating melts the polypropylene resin to form a continuous high-strength polyester fiber polypropylene reinforcement.

Embodiment 2

[0023] 150 parts of low-density polyethylene resin powder, 600 parts of PCS continuous high-strength polyester fiber, and 100 parts of talcum powder are made into prepreg by powder adsorption method, and the polyethylene resin is melted by heating in an oven with a temperature of 155 °C. The prepreg is directly passed through the extruder die to form a secondary cladding material, and the die is a low-density polyethylene melt, wherein 5 parts of antioxidant 1010 and antioxidant 168 composite antioxidant system are added (per thousand part resin). The resin coating amount was controlled so that the resin content was 300 parts.

Embodiment 3

[0025] 800 parts of polypropylene resin powder and 200 parts of PCS continuous high-strength polyester fiber are made into prepreg by electrostatic adsorption powder impregnation method, and the polypropylene resin is melted by heating in an oven at 195°C to form continuous high-strength polyester fiber Polypropylene reinforcement.
