Deep-Core Photocuring of High-Performance Adhesives

The next generation of military aircraft is heavily dependent on advanced composite materials to achieve the necessary performance. Many of these materials exceptional thermal insulators and, in addition, are susceptible to damage by excessive heat. Theneed is recognized for a new approach to deep-core curing of adhesives that will eliminate current surface heating method. Cornerstone Research Group, Inc. (CRG) proposes to design, fabricate, and demonstrate a novel Photodelivery System that will curecurrently qualified aircraft repair adhesives.During the Phase I effort, the viability of utilizing the Photodelivery System to cure adhesives was demonstrated. In the Phase II program, we will deliver a prototype Photodelivery System that could be easily transitioned into a commercial product forboth military and commercial markets.For the Phase II program, we have teamed with Boeing and Dexter Aerospace Adhesives. Boeing will provide insight into the needs of the aerospace end-user; while Dexter will provide insight into the needs of an aerospace adhesive manufacturer.
