A method for manufacturing a composite shaft comprising providing an impregnated fibrous material comprising a fiber impregnated with a hardenable polymeric material, forming an impregnated fiber preform by wrapping the impregnated fiber material around a shaped pressurizable bladder, the bladder having outer dimensions to form a preform dimensioned closely to the final dimensions of the shaft and dimensioned to allow placement of the assembly of the bladder and the impregnated fiber preform into female tooling, placing the assembly of the bladder and the impregnated fiber preform into the female tooling, pressurizing the bladder to press the impregnated fiber against the tooling, and heating the tooling to form a hardened composite of the polymeric material and the fiber while maintaining pressure in the bladder, releasing the pressure in the bladder, and removing the bladder from the interior of the shaft.
