PURPOSE:To extremely lighten the subject wheel by forming as core materials plastic foam into a disc, and adhering fiber reinforced plastic discs onto either surface thereof so as to make it into a disc, and then fixing the disc and a peripheral rim by the use of fiber reinforced synthetic resin. CONSTITUTION:Surface materials 1 made of a fiber reinforced plastic disc and core materials 2 are adhered in use of an adhesive agent, adhesive sheet or the like, or the surface materials 1 and core materials 2 are molded integrally in order to obtain a disc wheel main body. Subsequently, the honeycomb exposed parts of its end surface are filled with a putty material or the like and then made flat, following this, reinforcing fiber cloth and roving, or prepregs and the like are wound therearound for constituting a rim part 3 having predetermined structural strength and rigidity. And, after curing and finishing, it is made into a wheel. Thereby, a greatly light wheel having high rigidity and strength can be obtained. |
