PURPOSE:To produce a molding which has excellent mechanical and thermal properties and good dimensional stability and suffers little warpage deformation, by molding a mixture of glass fiber-contg. polyamide compsn. granules and mica-contg. polyamide compsn. granules. CONSTITUTION:10-60wt% glass fiber and 90-40wt% polyamide such as nylon 66 are mixed, melt-kneaded, and molded into a rope, which is then cooled and granulated to obtain glass fiber-contg. polyamide compsn. granules (a). 10- 60wt% mica and 90-40wt% polyamide are mixed, melt-kneaded and molded into a rope which is then cooled and granulated to obtain mica-contg. polyamide compsn. granules (b). Components (a) and (b) are mixed in such a proportion as to satisfy relateinship I and II (wherein A is wt% of glass fiber and B is wt% of mica). The mixture is molded.
