PURPOSE:To obtain a laminated product having heat resistance, rigidity and good visual appearance, by blow-molding by the use of a composite composed of polyamide resin, glass fiber and mica as an inner layer, and a composite of aliphatic polyamide and aromatic polyamide as an outer layer. CONSTITUTION:An inner layer is a composite composed of polyamide resin of 100 pts.wt., glass fibers of 5-40 pts.wt. and mica of 0-30 pts.wt. An outer layer is a composite composed of aliphatic polyamide of 95-0weight% and, aromatic polyamide of 5-100weight% which is composed of polyamide forming components of aliphatic diamine, isophtalic acid and/or telephtalic acid of 100-60weight% and aliphatic polyamide forming components of lactam or aliphatic diamine and aliphatic dicarboxylic acid of 0-40weight%. The above inner and outer layers are blow-molded. Thus, a molded product having the thickness ratio of the inner and outer layers of 1/1-100/1 and the average thickness of the outer layer of 2-0.05mm is obtained. |
