Abstract
Under the auspices of The Technical Co-operation Program (TTCP), Technical Panel MAT-5 (Nondestructive Evaluation for Ageing Military Systems) has undertaken an Operating Assignment to evaluate nondestructive inspection procedures appropriate for the detection of flaws in ceramic matrix composite materials (CMC's). In support of this effort, Canada has been supplied with three CMC tile specimens for the purpose of applying available inspection methods for technique development. The results of the various nondestructive inspections performed by the TTCP member nations will be further correlated with extensive destructive testing in order to determine the structural defects that will correspond to the NDE observations. High resolution ultrasonic imaging techniques were developed and applied to each of these specimens. Compton backscatter radiographic imaging was also applied, but wihtout success in the detection of processing abnormalities that may have occurred during the manufacture of these specimens. It is the purpose of this report to describe the nondestructive analyses that were performed by Canada on these three CMC specimens.
