Abstract
A method and associated system for repairing a reinforced polymer-infused fiber composite. The method includes providing a resin infusion device having resin components contained in a flexible, sealed container, positioning a dry fiber reinforcement onto a base layer repair location, providing at least one resin conduit connecting the resin container to a first end of the dry fiber reinforcement, providing at least one vacuum conduit connecting a vacuum source to a second end of the dry fiber reinforcement, covering and sealing the base layer repair location with a vacuum enclosure affixed to the base layer repair location, creating a vacuum environment at the base layer repair location via the vacuum conduit, infusing the dry fiber reinforcement with a reactive mixture of the resin components under vacuum conditions via the resin tubing to form a resin-infused fiber reinforcement, and curing the resin-infused fiber reinforcement inside the vacuum enclosure.
