Abstract
In this study, the use of an ultrasonic nondestructive evaluation technique and the principle of signal phase alteration are discussed. Combining them together, we can investigate the free edge effect, the transverse fiber/matrix interfacial failure, and the fiber breakage associated with the fiber fragmentation process for a single fiber composite. Using this method, we successfully detected composite fiber/matrix interfacial microscopic failure, which is much smaller in dimension than the ultrasonic wave focal area.
