Abstract
It is useful to detect defects of a preform for resin transfer molding before and after placement into the mold. To conduct this test, the gas flow method has been developed. This method not only measures permeability but also detects defects utilizing the pressure readings obtained from the gas flow test. This paper introduces the methodology and examine the applicability to actual processes.
