Abstract
A system for validating seal integrity includes a part forming tool having a supporting surface against which a composite part is formed and a surrounding surface. A caul sheet overlays the part. A vacuum bag is coupled to a perimeter of the caul sheet and disposed against the surrounding surface. The vacuum bag is coupled to the surrounding surface via an outer seal and an outer vacuum chamber is defined between the surrounding surface and the vacuum bag. An inner seal couples the vacuum bag to a perimeter of the caul sheet such that an inner vacuum chamber is defined between the caul sheet, the vacuum bag, and the supporting surface. A flow sensor is fluidically coupled with each vacuum chamber. A valve is selectively operable to fluidically couple and decouple the chamber and the vacuum source and/or to fluidically couple and decouple the chamber and an atmospheric pressure source.
