Fiber reinforced composite shaft with metallic connector sleeves mounted by longitudinal groove interlock

摘要

A tubular fiber reinforced composite shaft is formed (as described) which integrally incorporates a metal sleeve or connection at the end thereof. Initially a metal sleeve having circumferentially spaced recesses on the outer periphery thereof is positioned upon a segment of a mandrel. Fibrous material bearing a non-solidified resinous material is applied around the mandrel and around the recesses in the sleeve. Portions of the previously applied fibrous material bearing the non-solidified resinous material are pressed into the recesses. Additional fibrous material bearing the non-solidified resinous material is applied to the previously applied fibrous material. The resinous material next is solidified to form a tubular composite shaft whereby a secure torsion-transmitting connection is made with the sleeve, and the mandrel is removed.
