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.

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.

What is claimed is: 1. A system comprising:a mandrel having a reinforcement zone;an infusion medium configured to create a resin flow path from a resin zone to the reinforcement zone;an envelope containing the infusion medium and substantially covering the mandrel; anda vacuum cup entirely outside of the envelope for controlling pressure at an outer portion of the envelope at the resin zone, wherein the vacuum cup is configured to allow a pressure differential to be applied between the outer portion of the envelope and the resin under the envelope and also to allow pressure on the resin to be controlled independently from a compaction pressure.
