ABSTRACT:
A resin transfer molding system includes a plurality of ports for injecting resin into reinforcement material, which preferably comprises fabric, disposed between upper and lower mold pieces to form a structural part. Channels are provided adjacent the fabric reinforcement material and act as reservoirs to permit relatively fast and efficient injection of the resin without excessive applied pressure.
