Abstract
Technologies for reducing the risk of disbonding between two bonded members at areas of differing strain in the members are provided. Where the difference in strain between the two bonded members becomes excessing, movement of the members relative to each other may cause a traditional rigid adhesive to fail, resulting in a disbond or delamination in one or both composite members at the point of differing strain. Disbonding may be minimized or prevented by placing a compliant material, such as a thin sheet of rubber, between the structural members at the point of differing strain. The compliance of the material may allow the compliant material to deform enough to remain bonded to both structural members when subjected to a stress that might otherwise disbond or delaminate the bonded members.
