Abstract
A hybrid propeller shaft may include a CFRP tube layer in which high-strength CFRP or high-elasticity CFRP, the high-strength CFRP, and the high-elasticity CFRP are laminated to form at least two layers while having different wrapping angles by a prepreg wrapping process method; and a protective layer which is formed on an outermost layer of the CFRP tube layer to protect the CFRP tube layer.
