Abstract
Method and apparatus for use in curing of a composite charge having an internal cavity. Apparatus includes a flexible bladder adapted to be placed in the cavity for applying pressure on the composite charge during curing. An end fitting is operatively coupled to the flexible bladder. The end fitting defining a bolt bore and a horizontal bore. When a vent bolt is operatively coupled to the bolt bore of the end fitting, the vent bolt and the horizontal bore define a pressure passageway that allows an interior of the bladder to become subjected to external pressure.
