ABSTRACT:
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 apertures is positioned upon a segment of a mandrel. Fibrous material bearing a non-solidified resinous material is applied around the mandrel and around the apertures in the sleeve. Sharpened spikes are pressed through the fibrous material and into the apertures of the sleeve. Additional fibrous material bearing the non-solidified resinous material is applied around the outer ends of the spikes. 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.
