VACUUM BAG-LESS COMPOSITE REPAIR SYSTEMS AND METHODS

Abstract:

Described are methods and systems for repair of composite components without the use of vacuum bagging, The systems described herein include a composite repair structure with a repair laminate and a film sealant. The film sealant covers the repair laminate to prevent intrusion of air and other volatiles during bonding of the composite repair structure to the composite being repaired. As the film sealant prevents intrusion of air and other volatiles, the composite repair structure can be bonded to the structure to be repaired without the use of a vacuum bag. Thus, vehicle components can be repaired without disassembly from the vehicle.
