Superior structural performance of composites has been widely known to the aircraft industry for a long time now. The availability of advanced composite materials and a wide variety of material forms have attracted aircraft designers to adopt composites for the development of large primary and secondary aircraft structures. This growth of composites technology has and their acoustic signatures as they occur in laminated composites. Traditionally, the role of Non-Destructive Testing in quality assurance has been limited to defect detection. With advances in technology, Non-Destructive Testing has evolved into a multi-disciplinary science and has a critical role in ensuring quality and reliability. Of all the available Non-destructive Testing techniques, Acoustic Emission (AE) is probably the only technique that can be applied for monitoring damage initiation and propagation in real-time. Researchers have verified AE as a successful technique for detecting different micro-failures necessitated improvements in quality assurance during both manufacturing and in-service.
