Replacing composite bodies by the conventional metallic bodies have many advantages because of high specific
strength and high specific stiffness of the composite materials. As compared to the conventional drive shafts, Composite drive
shafts have the potential of lighter and longer life with high rotational speed. Nowadays drive shafts are used in two pieces.
However, the main advantage of the current design is that only one piece of composite drive shaft is possible that fulfils all the
drive shaft requirements.
