A drive shaft assembly comprising: a tubular, fiber-reinforced plastic shaft portion having layers of oppositely angled resin-impregnated helical fibers at 25°-65°to the longitudinal shaft axis and at least one layer having substantially longitudinal fibers forming a laminate, at least one layer of said laminate having an interior bonding surface, a metallic sleeve received within at least one end of said laminate and having an exterior bonding surface bonded to said interior bonding surface; said shaft portion having an inner spiral layer of closely wound fibers at 80°-90°to the longitudinal shaft axis, said layer terminating at the inner edge of said sleeve; whereby said layer of longitudinal fibers provides flexural rigidity to the laminate, said oppositely angled layers provide torsional strength while allowing radial contraction thereof to grip the sleeve, and said inner spiral layer provides additional hoop strength to the laminate.
