Continuous fiber reinforced thermoplastic composite material (CFRTP) has significant light weight, high strength, safety, environmental protection, and recyclability.

The project adopts self-synthesized branched high-fluidity nylon 6 resin and adopts the technical route of melt film molding and impregnation of continuous glass fiber fabrics, breaking through the technical bottleneck of the preparation and application of CFRTP materials, and forming the following innovations: First, independent research and development High-fluidity nylon 6 resin with controllable branched molecular structure and prepared into a film ; second, glass fiber surface treatment agent is compounded to improve the compatibility of fiber resin interface ; third, multi-layer fabric and nylon film are developed Synchronous laying technology optimizes the production process and equipment ; the fourth is the optimized design, which solves the problem of industrial production of lightweight structural parts with dual composite reinforcement systems.

This technical achievement has been applied in engineering applications in all-plastic car pedals, leaf spring pads, seat bending arms, rail transit lines and vehicle products, and has successfully replaced foreign imports with significant economic benefits.

The achievement has been appraised by the China Petroleum and Chemical Industry Federation, and the overall technology and product performance have reached the international advanced level, among which the preparation and application technology of the high-fluidity nylon resin and its membrane is at the international leading level.
