| Résumé : |
Lightweight, polymer matrix composites (PMC's) are an enabling material for Naval aircraft providing a combination of high stiffness to weight ratio and improved corrosion and fatigue resistance. In service Navy aircraft which incorporate extensive composite structure, though, are often subject to impact related damage resulting in various defects in the components which need to be repaired. Bonded patch repair processes are a preferred field repair solution (versus bolted repairs) as the resulting repair joint can obtain the stiffness and strength of the original part skin if performed correctly. Obtaining quality bonded repair joints becomes increasingly difficult, though, as the complex curvature of the part increases, even when using wet layup, fabric based laminate patches. This preliminary study evaluates the benefits of utilizing a new aligned, discontinuous "formable" textile called DiscoTex® (in development by Pepin Associates) for producing laminate patches for bonded repairs on select double curvature composite shapes typical of those geometries found on fixed wing fighter aircraft. |
