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 longitudinal grooves is positioned upon a segment of a mandrel. The grooves are inclined in a direction extending longitudinally inwardly and radially outwardly. Fibrous material bearing a non-solidified resinous material is applied around the mandrel and around the grooves in the sleeve. An annular lock ring having radially inwardly projecting ridges is inserted axially over the fibrous material whereby the ridges press the fibrous material into the grooves in the sleeve. The resinous material is then solidified to form a tubular composite shaft whereby a torsion-transmitting connection is made with the sleeve.
