Abstract: Vacuum assisted resin transfer molding techniques are improved by mounting a rigid external shell on top of a vacuum bag. The shell is sealed around the vacuum bag so that a vacuum is created between the shell and the vacuum bag, the vacuum causes the vacuum bag to be freely stretched and lifted away from the preform to create a flow flooding chamber which provides a flow channel on the top face of the preform to accelerate the resin flow and reduce the injection time.
