▎ 摘　　要

NOVELTY - Preparing thermoplastic graphene modified polyamide fiber comprises (a) preparing a graphene dispersion liquid, (b) mixing and reacting the obtained dispersion with caprolactam to obtain a graphene toughened polyamide slice, and (c) melting and spinning obtained slice. USE - The method is useful for preparing thermoplastic graphene modified polyamide fiber, which is useful in electronic, automobile, aerospace, national defense military industry, nuclear energy industry, bulletproof and building industries. ADVANTAGE - The thermoplastic graphene polyamide fiber has excellent mechanical property, compatibility with the reinforced fiber, and ballistic protection performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a fiber co-woven reinforced composite material; and a method for preparing fiber co-woven reinforced composite material. DESCRIPTION OF DRAWING(S) - The drawing shows the fiber co-woven reinforced composite material three-dimensional fabric weaving structure section sketch map. 1Thick joint warp 2Weft yarn 3Pad warp
