NOVELTY - Enhanced composite material with high rigidity and low warping comprises 50-70 pts. wt. nylon resin, 3-9 pts. wt. glass fiber, 4-10 pts. wt. steel fiber 4-12 pts. wt. nano-talc powder, 4-10 pts. wt. sodium fluorosilicate, 4-12 pts. wt. nano-zinc oxide, 1-3 pts. wt. flame retardant, 2-4 pts. wt. composite inorganic filler, and 4- 10 pts. wt. carbon nanotubes. USE - High-rigidity low-warping reinforced composite material used in electric appliance, chemical industry, medical treatment, mechanical industry. ADVANTAGE - The composite material has high structure strength, not easy to warp, has high rigidity and toughness, bending strength, bending modulus, makes the size stability of the composite material, and improves anti-warping property; glass fiber steel fiber can further enhance the toughness of the composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation method of the high-rigidity low-warp reinforced composite material, which involves adding nylon resin, glass fiber, steel fiber, nano talcum powder, sodium fluosilicate, nano zinc oxide, mixing fire retardant in mixer to obtain mixture A; adding composite inorganic filler in the mixture A, carbon nano tube, after mixing, adding vibration dispersion machine for dispersion treatment to obtain mixture B; and adding the mixture B into the double-screw extruder to extrude to obtain composite material.
