System and method of detecting air leakage in a VARTM process

摘要

A method of detecting leakage from a preform used in a VARTM process includes providing a mold and bagging film suitable for use in the VARTM process; heating air; distributing hot air along an interface between an the bagging film and a surface of the mold; determining a temperature distribution along the interface; and using the temperature distribution to locate one or more leaks in the bagging film.
