To obtain the subject composite having low specific gravity and excellent in fatigue resistance, stiffness, strength, etc., by including plural polyamide components having different melting points into a matrix comprising a polyamide component with lower melting point so as to disperse a polyamide component having higher melting point in fibrous state.
This polyamide composite contains plural polyamide components having different melting points so as to disperse (B) a polyamide component having higher melting point (e.g. nylon 6), preferably 130-220°C melting point into (A) a matrix comprising a polyamide component having lower melting point, preferably 190-270°C melting point in the state of fiber having ≤1.0 μm average fiber diameter. The ratio of polyamide components is preferably 50-100 pts.wt. component B to 100 pts.wt. component A. The composite is useful for bumpers and interiors of automobiles and exteriors and parts, etc., of household appliance products.
