ABSTRACT:
A resin transfer molding system and method provides for injecting resin into fibrous material disposed on the inner surfaces of a pair of mold pieces. The mold pieces are shaped to form a structure with two sections which extend in at least two different planes. An inflatible member in one of the sections forces a second pre-inflated member into the second section prior to the injection of resin into the fibrous material.
