Studies to establish such long-term durability of candidate materials for supersonic commercial aircraft were recently conducted. Results of residual mechanical properties from tests of a candidate PMC material subjected to a realistic thermal-mechanical environment for time periods up to 15,000 test hours are presented. Property changes, as measured by mechanical tests of coupons, are presented as a function of the number of aging hours and aging conditions. Analysis of these comparisons has provided the data to assess the relative importance of each experimental factor. The different degradation mechanisms are assessed and their impact on material performance are ranked according to exposure time and test conditions.
