Abstract

Polymer-matrix composites are susceptible to interlaminar delaminations, fiber fractures, matrix cracking, fiber/matrix debonding, and other damage that can degrade structural performance. Such damage can occur during manufacture, assembly, and/or normal service, and may have an influence on usage and repair decisions. It is,therefore, important to be able to nondestructively inspect and characterize damage in fiber-reinforced materials. Ultrasonics represents a state-of-the-art technique for performing such inspections. Recent advances in transducers, instrumentation and scanning hardware have increased the effectiveness of this method of detecting and characterizing flaws.
