Abstract:
A laminated product formed by laminating a urethane resin layer on a fiber-reinforced resin layer having two or more layers and being obtained by laminating two or more prepreg sheets so as to intersect fiber directions at right angles or being obtained by laminating two or more prepreg sheets so as to intersect fiber directions at right angles and laminating a non-woven fabric on one or both surfaces of the resulting laminated prepreg sheets, wherein said prepreg sheets have a thickness of 50 to 1,000 &mgr;m and are obtained by arranging a continuous reinforcing fiber in one direction and impregnating the arranged continuous reinforcing fiber with thermoplastic resin so that said continuous reinforcing fiber is present in a amount of 40 to 80% by volume, said laminated product having a linear expansion coefficient of 2.0Ã—10âˆ’5/Â° C. or less when measured at 0Â° C. and 50Â° C. and a thermal dimensional variation of 0.1% or less in dimensional stability for the two fiber directions of the laminated prepreg sheets.
