Abstract
A pressurizable bladder for the manufacture of a composite shaft manufactured from a flexible elastomeric material and adapted for supporting at least one layer of fiber impregnated with resin has an opening for pressurization of the bladder to compress the impregnated fiber against female tooling while the tooling is heated to cure the resin. The bladder has a wall of variable thickness to permit outer contours of the bladder to conform to inner contours of the female tooling.
