Abstract
A composite tubular structure, such as a vehicle drive shaft. The ends of a fiber reinforced resin tubular member are formed with a plurality of longitudinal slots and each slotted end of the tubular member is positioned in overlapping relation with a cylindrical sleeve portion of a metal yoke. A cylindrical metal collar is disposed around the overlapping joint and spaced portions of the collar are deformed inwardly by electromagnetic energy into contact with the sleeve of the yoke. The deformed portions can be mechanically interlocked with the sleeve by welding or the like. With this construction, the torsional load is transmitted through the deformed portions of the collar and the edges of the tubular member bordering the slots to provide an improved mechanical connection between the fiber reinforced tubular member and the yokes.
