Abstract
A composite lightweight wheel rim for spoke wheels having an inner and an outer ring separated by a low density rigid foam core. The inner and outer rings are formed from a composite fiber/resin material having the fibers positioned in a predetermined orientation. This structure forms a stiff, lightweight wheel rim suitable for many spoked wheel applications.
