Abstract
Abstract A method for joining a fiber-reinforced plastic structure to a metallic insert for fitting around a rotary shaft is disclosed. The method comprises winding a resin-impregnated strand of continuous long-staple fibers around an engaging means formed on the metallic insert thereby effecting the desired union. By this method, a rotatable element such as a wheel, a hand-wheel or the like, such as a steering wheel can be produced.

A method for making a rotatable element including a metallic insert, a rim portion and spokes connecting the insert and rim portion, said method comprising the steps of: (i) winding a resin-impregnated strand of continuous long-staple fibers around an engaging member formed on a fitting means in the form of a metallic insert by winding said resin-impregnated strand of continuous long-staple fibers in a repeated pattern around a substantial circumferential portion of said insert while placing said fibers in a zig-zag pattern about a multiplicity of radially extending engaging pins provided on said metallic insert; and (ii) forming said spokes and rim with said strands, said spokes extending outwardly from said metallic insert.
Claim 2
Independent Claim
