Abstract
High temperature fiber reinforced ceramic matrix composites (CMC's) show much promise for application in current and future generation aeropropulsion systems. These materials systems possess a combination of properties: light-weight, high strength, high temperature capability, and non-brittle failure mode; not possible with any other class of material. However, the turbine hot section is a very harsh environment and current development work has shown that these materials may suffer for environmental degradation during service. The successful application of these materials in man- rated engines requires that the factors contributing to material degradation be recognized, and accounted for. The many possible material combinations and application-specific thermo-mechanical-environmental service conditions renders the development of a purely empirical approach extremely time-consuming and expensive. An alternative approach is to develop some form of mathematical model able to predict material durability based on a knowledge of the material constituents and the general operating conditions (time, temperature, load, etc.). The opportunity presented by this proposal is to demonstrate a micro-mechanics approach to durability modeling to allow the prediction of composite mechanical performance as a function of time, temperature and mechanical loading condition.
