Abstract
Innovative research and development leading to a dual-use advanced technology product is proposed. The product is a methodology and associated software for design and life prediction of ceramic matrix composite (CMC) propulsion components with and without environmental barrier coatings (EBCs). The methodology would be applicable to a broad class of CMCs for military and commercial applications. A Physics-Based mechanistic modeling approach is proposed to minimize the need for extensive long term testing of CMCs, while providing a pragmatic approach for cost effective material selection and design for long-term durability under severe thermal gradients. The approach includes direct consideration of relevant damage mechanisms and environmental degradation. Phase I will involve characterization of the mechanistic model for CMC materials selected by GE Aircraft Engines. The models will then be used for predicting the outcome of selected benchmark and sub-element tests. Predictions will be compared with experimental measurements to assess the modeling approach and feasibility for a comprehensive methodology development in Phase II. The proposed product is a comprehensive design and life prediction methodology and associate software for its implementation.
