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.

A hollow tubular reinforced composite shaft comprising: a shaft body comprising a plurality of integrally bonded circumferential plies of solidified fiber reinforced resinous material; a metal sleeve mounted in at least one end of said shaft body, said sleeve including a plurality of circumferentially spaced, longitudinally extending grooves on an outer periphery of said sleeve; said grooves each being inclined in a direction extending longitudinally inwardly and radially outwardly; an annular lock ring positioned upon said sleeve and upon said plies of fibrous material disposed therearound, said lock ring including a plurality of circumferentially spaced, longitudinally extending ridges on an inside periphery thereof; said ridges each being inclined in a direction extending longitudinally inwardly and radially outwardly, and being disposed in overlying relation to said grooves in said sleeves to press portions of said fibrous material into said grooves thereby forming a torsion-transmitting connection therebetween.
