Abstract

The invention relates to a continuous fiber fabric reinforced thermoplastic polyurethane composite material and a preparation method thereof. The composite material is prepared by heating, curing and cooling a continuous fiber reinforced fabric which is steeped in thermoplastic polyurethane elastomer reaction liquid, wherein the continuous fiber reinforced fabric is selected from one or more of organic fibers, metal fibers or inorganic fibers, and the thermoplastic polyurethane elastomer reaction liquid is formed by polymerizing a polyether component and an isocyanate component. Compared with the prior art, the continuous fiber fabric reinforced thermoplastic polyurethane composite material prepared by using the continuous fiber reinforced fabric as a reinforcing material and a thermoplastic polyurethane elastomer as a reinforced matrix has the advantages of good steeping, low porosity, adjustable thickness, high glass fiber content and the like. The preparation method has the advantages that the production line is simple, equipment can realize the high-efficient continuous production, no environmental pollution is caused in the production process and the like.

Description

technical field [0001] The invention relates to a polymer composite material and a preparation method thereof, in particular to a continuous fiber fabric reinforced thermoplastic polyurethane composite material and a preparation method thereof. Background technique [0002] Fiber-reinforced thermoplastic composites have excellent performance and can be reused. In recent years, they have been used more and more in daily life. There are many studies on chopped fiber reinforced thermoplastic composites, such as patent US3684645, which uses chopped fiber and thermoplastic resin to be combined and then enters a double-belt vulcanizer, heated and impregnated, and cut into required sheets. [0003] There are many studies and applications of this kind of fiber reinforced thermoplastic composites abroad, such as patents US4098943 and US4469543, which introduce the composite of continuous fiber fabrics and extruded thermoplastic films or thermoplastic resin powders, and then heat, mel...
