Review of Progress in Quantitative Nondestructive Evaluation

One of the most challenging problems in nondestructive evaluation of composite materials is the inspection of the fiber/matrix interface. Addison and Sinclair studied the scattering spectra of silicon carbide fibers in titanium metal matrix composites at normal incidence [1]. Although they found that the frequency response of the embedded fiber is very sensitive to small changes in the interfacial bond, this technique cannot be easily adapted to multiple-ply composites. From this point of view, it is more promising to measure the velocity and attenuation of dispersive guided modes propagating along the fibers. It was pointed out by Drescher-Krasicka et ...
