Abstract
The invention provides a laminated product of urethane-based resin. That is, the invention arranges a continuous reinforcing fiber to one direction, impregnates the arranged fiber with thermoplastic resin to form a prepreg sheet having 50% in volume ratio of the fiber, laminates two or more resulting prepreg sheets so as to intersect fiber directions at right angles or further laminate of the prepreg sheet to form a fiber-reinforced resin layer, laminates a urethane-based resin layer on the resulting fiber-reinforced resin layer, and thus provides a urethane-based resin laminated product having excellent dimensional stability and application ability.
