OUT-OF-AUTOCLAVE HYBRID ADHESIVES FOR STRUCTURAL BONDING AND ON-AIRCRAFT REPAIR

This Phase II Small Business Innovative Research Program will mature, and transition to the Air Force, a novel class of high performance structural adhesives based on P2SI newly developed hybrid chemistry. These adhesives, and their ability to bridge major technology gaps in the current state-of-the art, were demonstrated in the Phase I program. These out-of-autoclave processable structural adhesives offer exceptional adhesive strength, toughness, environmental durability, versatility, and processing characteristics that enable rapid production rates for structural bonds, higher performance, increased durability, and on-aircraft repair capability previously unattainable for many aircraft structures. BENEFIT: Directly applicable to fielded military systems, the F-35, and commercial aerospace. These materials also have application for composite matrices for high performance out-of-autoclave structural materials.
