Title:
AIRCRAFT STRUCTURE WITH MEANS FOR REDUCING THE RISK OF DISBONDING IN AREAS OF DIFFERENT STRAIN
Document Type and Number:
WIPO Patent Application WO/2013/074174
Kind Code:
A3
Abstract:
Technologies for reducing the risk of disbonding between two bonded members (108, 110) at areas of differing strain in the members (108, 110) are provided. Where the difference in strain between the two bonded members (108, 110) becomes excessing, movement of the members (108, 110) relative to each other may cause a traditional rigid adhesive to fail, resulting in a disbond or delamination in one or both composite members (108, 110) at the point of differing strain. Disbonding may be minimized or prevented by placing a compliant material (208), such as a thin sheet of rubber, between the structural members (108, 110) at the point of differing strain. The compliance of the material may allow the compliant material (208) to deform enough to remain bonded to both structural members (108, 110) when subjected to a stress that might otherwise disbond or delaminte the bonded members (108, 110).
