RESEARCH AND DEVELOPMENT OF NONDESTRUCTIVE TESTING TECHNIQUES FOR COMPOSITES.
Abstract
Research was continued for the development of nondestructive testing techniques for fiber reinforced matallic matrix composites. A literature survey evaluation was conducted to determine the potential applicability of nonroutine inspection methods including neutron radiography, neutron activation, nuclear resonance, etc. Conventional radiographic, acoustic and electromagnetic inspection methods were applied to four composite material systems and evaluated in terms of defect detection and correlation with the material properties. Ultrasonic velocity measurments on boron filament provide property data as well as establishing the feasibility of conducting static or dynamic velocity-filament stress relationships.
