  • Bulk resin infusion
    Patent number: 10052826
    Abstract: A method for performing resin infusion into a dry reinforcement on a layup mandrel comprises placing resin at a resin zone on the mandrel; bagging the reinforcement and the resin with a bagging film; heating the resin while applying compaction pressure to the bagging film to cause the resin to be infused into the reinforcement; and creating a pressure differential outside of the bagging film over the resin zone to control rate and pressure at which the resin is infused into the reinforcement. As a result, the resin pressure and infusion rate are controlled independently of the compaction pressure on the reinforcement.
