Abstract

PURPOSE:To enhance the adhesion between metallic fiber and resin, and also the heat radiating performance or the like of a wheel, in the wheel for an automobile consisting of fiber reinforced resin, by forming a part or the whole of the reinforcing fiber with metallic fiber having recessed parts on its surface. CONSTITUTION:In order to obtain an automobile wheel 3, first, a sheet consisting of glass-fiber reinforced vinyl ester resin 1 or the like called, for example, sheet molding compound is cut into pieces of a prescribed size to form sheet materials. Next, the plural number of sheet materials are laminated, and further a prescribed amount of metallic fibers 2 having a large number of recessed parts 6 are arranged between respective layers to form laminated sheet materials. Subsequently, the laminated sheet materials are charged in a heated molding metal mold, and are compressively formed, so that the automobile wheel 3 in which the metallic fibers 2 are arranged so as to be nearly uniformly dispersed in the glass-fiber reinforced resin 1 can be obtained. Thus, the adhesive property between the glass-fiber reinforced resin 1 and the metallic fibers 2 can be enhanced.
