摘要

Ceramic matrix composites may contain numerous internal features that could potentially affect their mechanical performance during service application. Therefore, potential non-destructive investigation techniques for the evaluation of aluminium oxide/aluminium oxide ceramic matrix composites (CMC) are presented. Several different non-destructive evaluation (NDE) methods were assessed for their capability to identify the internal structure on varying scale lengths. Internal features of interest included artifacts from the manufacturing process such as porosity, delamination and microcracking. Artificial defects of varying size were also deliberately introduced within the CMC during the manufacturing phase, to establish a threshold of the resolution for each technique. The NDE methods selected included X-ray computed tomography, 2-D radiography, flash thermography, immersion ultrasonic and resonance testing. This allowed for the ranking of each NDE method and recommendations for their future cost effective employment.
