Abstract
A drive shaft of hollow form and of fibre-reinforced plastics material, has an end provided with an integral radially inwardly extending flange and one or more connecting members for effecting torque transmission with such flange. The flange may have a single central bush or the like, or a number of circumferentially distributed bushes, bolts or pins for torque transmission. Further a method of manufacturing such a drive shaft by fibre winding includes chordal winding of fibres to provide the flange, and a device for forming the flange during the winding process.
