<p><P>PROBLEM TO BE SOLVED: To provide a laminated molded article low in a linear expansion coefficient, lightweight, and excellent in impact resistance, durability, handling property, productivity or the like; and be preferably used as a cladding building material such as a rain gutter. <P>SOLUTION: The laminated molded article comprises laminating a thermoplastic resin layer on both sides of a thermoplastic polyester resin sheet having the linear expansion coefficient of -1.5×10<SP>-5</SP>or more and less than 0, and an elastic module in tension of 8 to 15 GPa. In addition, preferably the thermoplastic polyester resin sheet in an amorphous state is pultrusion-stretched through a pair of rolls having a glass transition temperature of the thermoplastic polyester resin sheet of -20°C to +20°C, and is laminated with the thermoplastic resin layer on both sides of the stretched thermoplastic polyester resin sheet obtained by mono-axially stretching at temperatures higher than the temperature of the roll. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
