Abstract
A composite part charge having an internal cavity is placed on a tool and covered by a vacuum bag for autoclave curing. A bladder is placed in the cavity to react autoclave pressure on the charge. The bladder is coupled with a flexible fluid reservoir located beneath the vacuum bag. The bladder is pressurized by autoclave pressure applied through the vacuum bag to the flexible fluid reservoir.
