Notes:
Several nondestructive evaluation (NDE) techniques, including ultrasonic C-scan, X-raycomputed tomography (CT), and infrared (IR) thermography, were employed on ceramic matrixcomposites (CMCs) to illustrate defect information that might effect mechanical behavior and toanalyze structural performance of CMCs. Prior to tensile testing, through C-scan and CT analysesresults, the qualitative relationship between the relative ultrasonic transmitted amplitude and porositybased on CT was exhibited. An IR camera was used for in-situ monitoring of progressive damagesand to determine temperature changes during tensile testing. Moreover, scanning-electronmicroscopy characterization was used to perform microstructural failure analyses. This paperdescribes the use of nondestructive evaluation (NDE) techniques to facilitate the understanding oftension behavior of CMCs
