Abstract
A method of forming a composite tubular structure, such as a drive shaft, composed of a tubular member formed of fiber reinforced resin and having metal yokes secured to the ends of the tubular member. Each yoke includes a cylindrical sleeve portion bonded in overlapping relation to the respective end of the tubular member. A plurality of longitudinally extending ribs or bosses are formed on each sleeve portion and are received in slots provided in the respective end of the tubular member. Windings of a fibrous material impregnated with a thermosetting resin can be applied over the joint between the tubular member and each sleeve portion. With this construction the torsional load is transmitted through the ribs and slots rather than through an adhesive bonded interface between the members.
