ABSTRACT:
A joint for connecting a first drive shaft to a second drive shaft includes a ball and socket arrangement connecting the two shafts and a spring attached at one end to one shaft and at the other end to the other shaft. The spring is made of a polymer matrix containing fibers made from poly(p-phenylene terephthalamide) resin. The fibers extend through the polymer matrix along the helical axis of the spring. The spring is disposed about the ball and socket arrangement so that shock loads are absorbed by the spring.
