PURPOSE:To obtain a plastic automobile oil pan excellent in heat resistance, rigidity, toughness, resistance to road antifreezer, etc., by molding a mixture of at least two specified polyamides with an inorganic reinforcement. CONSTITUTION:5-95wt.% polyamide (e.g., nylon 6) consisting mainly of capramide and/or hexamethylene adipamide units is mixed with 95-5wt.% polyamide (e.g., nylon 12) obtained by melt-polymerizing at least one member selected from among a 1-12C aliphatic amino acid, a lactam and a equimolar salt of a 6-12C aliphatic diamine with a 6-12C aliphatic dicarboxylic acid (except hexamethylenediammonium adipate). 100pts.wt. this mixture is mixed with 0-100pts.wt. inorganic reinforcement (e.g., glass fiber), and the obtained mixture is molded into an automobile oil pan. |
