Abstract:
A device for detecting an air leak in a tool comprises a vacuum bag and a leak detection film disposed along an inside face of the vacuum bag. The leak detection film may include oxygen sensitive material configured to change physical appearance at a location of an air leak in the tool. A breather layer may be interposed between the tool and the leak detection film for facilitating air flow therebetween.
