NONDESTRUCTIVE EVALUATION (NDE) OF FIBERGLASS MARINE STRUCTURES STATE-OF-THE ART REVIEW; FINAL REPT

This report reviews the methods of nondestructive evaluation (NDE) of glass-reinforced plastics as applicable to common marine sandwich construction. Forty panels of various cored and solid construction were built with implanted defects, such as dry fibers, uncured resin, air gaps, delaminations, cracks and impact damage. The panels were then subjected to a variety of testing techniques such as ultrasonics, tapping, thermography, radiography and visual inspection. Some of the results are highly varied, pointing out the difficulty of locating certain defects and the comparative ease of finding others.
