Summary

Two types of nondestructive evaluation (NDE) techniques, including ultrasonic C-scan and X-ray computed tomography, were conducted on ceramic matrix composites (CMCs) to illustrate defect distributions that might effect mechanical behavior. Two types of CMCs specimens were chosen for NDE, woven Nicalon™ fiber reinforced SiC composites and 0/90 degree cross-ply composites. In this investigation, the relationship between the relative ultrasonic transmitted amplitude and porosity based on X-ray computed tomography was quantitatively formulated. Moreover, the correlation between ultrasonic C-scan and X-ray computed tomography has been developed to provide an understanding of the NDE of Nicalon™/SiC composites.
