发明名称 Process for Producing Oriented Thermoplastic Polyester Resin Sheet, and Laminate-Molded Body
摘要 The present invention provides a process for producing an oriented thermoplastic polyester resin sheet which is excellent in tensile strength, tencile modulas and heat resistance, and a light laminate-molded body using the same, which has a low linear expansion coefficient and is excellent in impact resistance, durability, easiness of handling, productivity, and others. A process for producing an oriented thermoplastic polyester resin sheet, which includes: pultrusion-drawing a thermoplastic polyester resin sheet in an amorphous state at a temperature from the glass transition temperature of the thermoplastic polyester resin-20° C. to the glass transition temperature of the thermoplastic polyester resin+20° C.; and then drawing the resultant uniaxially at a temperature higher than the temperature for the pultrusion-drawing. A laminate-molded body, wherein a thermoplastic resin layer is laminated on each of the surfaces of the resultant oriented thermoplastic polyester resin sheet.
