A Review of Issues and Strategies in Non-Destructive Evaluation of Fiber Reinforced Structural Composites

Abstract

This paper emphasizes the need for advanced nondestructive evaluation (NDE) techniques for quantitative assessment of the mechanical strength and integrity of fiber composites during manufacture and service and following repair operations. Problems and approaches are discussed relative to acceptance criteria, calibration standards, and methods for NDE of composites in strength-critical applications. It Is indicated that acousto-ultrasonic techniques provide the "methods of choice" in this area.
