Abstract

See full text

A drive shaft is for selectively connecting a drive input to an output. The drive shaft has a tubular portion, a first diaphragm member, and a second diaphragm member displaced axially along the shaft from the first diaphragm member. The first and second diaphragm members each are formed with two axial ends. At least one undulation extends radially of the ends. The tubular portion connects the first and second diaphragm members. The first and second diaphragm members and the tubular portion are formed of fiber-reinforced polymer matrix composites. The first and second diaphragm members are connected to first and second axial ends of the tubular portion through a mechanical connection at joints. There is also a method of forming a drive shaft.
