Abstract : Destructive and nondestructive evaluation (NDE) techniques for documenting defects and damage in resin-matrix composite materials are described and assessed from the viewpoint of a researcher studying the damage accumulation process. The results show that deploying, a destructive evaluation technique, provides the most detailed information on the spatial distribution of damage in resin-matrix composite materials. Of the NDE techniques, penetrant enhanced stereo x-ray radiography is the best one. Ultrasonic, holographic, and edge replication NDE techniques provide much less information than x-ray radiography. Acoustic emission, thermographic and stiffness change monitoring provide valuable information on when to conduct more thorough evaluations using one of the other NDE techniques.
