PURPOSE:To provide the titled resin compsn. which hardly cause warpage, has excellent resistance to antifreezing soln. and oils and is suitable for use as a material for automobile parts, by blending an inorg. reinforcing material with a polyamide mixture of nylon 46 and a non-crystalline arom. polyamide. CONSTITUTION:90-10pts.wt. nylon 46 obtd. by the polycondensation of tetramethylenediamine and adipic acid is mixed with 10-90pts.wt. non-crystalline arom. polyamide obtd. by the polycondensation of terephthalic acid and/or isophthalic acid with trimethylhexamethylenediamine and/or hexamethylene- diamine. 20-100pts.wt. inorg. reinforcing material is mixed with 100pts.wt. resin mixture to obtain the desired reinforced polyamide resin compsn. Examples of the inorg. reinforcing materials are glass fiber, carbon fiber, mica, silica and calcium carbonate.
