Description

technical field

[0001] The invention relates to a polyamide composite material and a preparation method thereof, which can be used for injection molding and extrusion to manufacture military products, aerospace devices and sports medical devices, and belongs to the technical field of polyamide materials. Background technique

[0002] Carbon fiber-reinforced composites have the advantages of light weight and high mechanical properties, especially flexural modulus or stiffness. To minimize weight, carbon fiber-reinforced materials are traditionally made using epoxy resins without fillers. Due to the use of hand lay-up or resin transfer molding processes, the material is often used to manufacture low-volume aerospace components, racing cars and other special products. However, the high cost of epoxy resin and the labor-intensive hand lay-up process limit the use of carbon fiber composites in industrial-scale applications. Due to the surface bonding ability of thermoplastics and...
