Abstract A composite wheel, for a heavy duty vehicle, having a barrel member with an inner layer of laminated tape structure wound on an out of round shaped mandrel. The barrel member has a plurality of formed sections of chopped fibers in an epoxy resin. The inner surface of each section conforms to the out of round tape structure and the outer surface forms the tire bead retainers and drop center portion of the wheel. An outer layer of laminated tape structure surrounds the formed sections. A wheel web member, made of chopped fibers in an epoxy resin has its outer surface conforming to the out of round configuration of the barrel member. The web member is made of two sections which are secured to the barrel member.
The method for constructing heavy duty wheels for vehicles, comprising: forming a barrel member by winding an inner layer of predetermined thickness of filament reinforced epoxy resin tape on a mandrel having a symmetrical out of round outer surface; subjecting the inner layer to a precure compaction stage; positioning a plurality of partially cured preformed segments of chopped fiber reinforced epoxy resin, having their inner surface conforming to the out of round configuration of the inner tape layer and their outer surface conforming to the desired tire receiving configuration of the wheel, around the periphery of the tape layer; winding an outer layer of a predetermined thickness of filament reinforced epoxy resin tape around the outer surface of said segments; subjecting the outer layer to precure compaction stages after each predetermined number of thicknesses of tape; curing the barrel member within a form in an autoclave at a predetermined temperature and pressure; removing the barrel member from the autoclave; allowing the barrel member to cool; securing a two part hub member within the barrel member with an epoxy adhesive.
