To assess the condition of the SiC/SiC liners after combustor testing, their mechanical properties were measured. Specimens were machined from two of the sector rig components, the lean transition liners (LTLs) and the lean zone inner diameter liners (LZIDs) that were tested for various times to obtain post-exposure strengths. The average strength for the LTLs tested up to 260 hours was the same as average strengths obtained from witness coupons machined from the as-manufactured components. However, for the LZIDs, post exposure strength decreased with increasing exposure time. In addition, NDE results from the as-manufactured components were compared to post-exposure NDE. The techniques employed were able to image significant damage in these combustor liners that manifest itself as low post-exposure strength. The thermography and ultrasonic techniques were particularly effective in finding damage in the lean zone inner diameter liners.
