Problems solved by technology

[0002] Continuous fiber reinforced thermoplastic prepreg composite materials have been widely used in the fields of automobiles, machinery, electronics, electrical, chemical, building materials and military industries in my country, replacing a large number of non-ferrous metal parts, and even some ferrous metal parts, such as the Chinese patent CN102295792A discloses a continuous fiber-reinforced thermoplastic flame-retardant prepreg composite material and its preparation method, which is made of modified resin and continuous fibers. Although the composite material has good flame-retardant and impact-resistant properties, it is not widely used in coal mines in my country. The application in the industry is limited, the main reason is that the surface resistance of engineering plastics is large, and it is easy to generate static electricity. If it is used underground in coal mines, it will inevitably cause danger. Therefore, the MT113-85 standard "Coal Mine Continuous fiber-reinforced prepreg composite materials required by the "Code for Inspection of Non-metallic Materials for Downhole Use" are imperative

Abstract

The invention belongs to the field of processing of high polymer materials and relates to a continuous-fiber-reinforced thermoplastic composite material and a preparation method thereof. The continuous-fiber-reinforced thermoplastic composite material is prepared from the following components by weight: 45 to 55 parts of modified resin and 45 to 55 parts of continuous fibers. Compared with the prior art, the method overcomes liquidity of resin and wettability of fibers; produced prepreg not only has high strength, but also is good in flame retardance and antistatic property, and has higher applicability.
