REPAIR OF AIRCRAFT STRUCTURES

Abstract

Composite materials are only one of the types of materials used in the aeronautical field, but their use has progressed dramatically over the last decades. Knowing that an aeronautical program is developed over an average of ten years, and a time necessary to study, test, and launch the industrialization of an aircraft, improving its aerodynamic quality, while increasing the performance of engines and especially reducing the weight of structures. On the other hand, non-destructive testing (NDT) plays a very important role in detecting or characterizing the defects existing in the composite structure, estimating the importance of damage as well as determining the quality of a repair. However, the purpose of this study is to characterize some existing defects in the composite structure commonly used in aeronautical manufacturing, by representing the less expensive repair methods, to reduce the overweight of the final repair.
