BLADDER SYSTEM FOR CURING COMPOSITE PARTS

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for use in curing a composite charge having an internal cavity.SOLUTION: An apparatus includes a flexible bladder 55 adapted to be placed in a cavity 45 for applying pressure on a composite charge 10 during curing operation. An end fitting 200 is operatively coupled to the flexible bladder 55. The end fitting 200 defines a bolt bore 260 and a horizontal bore. When a vent bolt 300 is operatively coupled to the bolt bore 260 of the end fitting 200, the vent bolt 300 and the horizontal bore define a pressure passageway that allows an interior of the bladder 55 to become subjected to external pressure.SELECTED DRAWING: Figure 7
