This invention discloses a polyamide composite material, comprising the following components by weight: 70-94 parts polyamide resin; 0.1-1 parts rice bran wax metal salt; and 5-30 parts toughening agent. The polyamide is selected from copolymer polyamide resin, or a blend of copolymer polyamide resin and homopolymer aliphatic polyamide resin, wherein, when copolymer polyamide resin and homopolymer aliphatic polyamide resin are blended, the copolymer polyamide resin accounts for 5-95 wt% of the polyamide resin. This invention utilizes a specific type of polyamide and rice bran wax salt as a nucleating agent to reduce crystal size. The combined effect results in polyamide grains with a size smaller than the visible light wavelength, increasing crystal density and enabling absorption of visible light by the grains. When the polyamide composite material is bent under stress, the resulting micro-voids do not produce light reflection, thus significantly reducing the stress whitening defect of the polyamide composite material. Furthermore, the polyamide composite material of this invention maintains good mechanical properties.
