ABSTRACT:
A composite item is fabricated in a device for infusing a layup. The device include a mandrel, vacuum cup and bagging film. The mandrel is to receive the layup. The mandrel includes a reinforcement receiving zone and a resin receiving zone substantially adjacent to the reinforcement receiving zone. The vacuum cup is in cooperative alignment with the resin receiving zone. The bagging film is to generate a gas tight envelope surrounding the reinforcement receiving zone and the resin receiving zone. The vacuum cup is sealed upon the bagging film to generate a chamber above the resin receiving zone.
