ABSTRACT:
A molding obtained by laminating resinous plates of 0.05 to 1 mm thick, prepared by impregnating 20% by volume or more of a reinforcing fiber with a thermoplastic resin, and molding the resultant laminate, wherein sections where deviation or deformation is caused by an external force, or preferably nonjoining parts having an area of 5 to 60% based on the area of the location where impact is absorbed, are provided between the laminated layers constituting the molding, or the laminated layer surface where the impact is absorbed is formed with a shape having a curvature of 5 to 20 mm in radius. The molding absorbs impact force significantly and prevents efficiently human body, etc. from the shock upon striking.
