AbstractInnovative 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. The primary focus is on assessment of integrated Thermal Protection Systems (TPSs). However the methodology would be applicable to a much broader 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. The approach includes direct consideration of relevant damage mechanisms and environmental degradation. The project will involve characterization of the mechanistic model for selected CMC materials relevant to TPSs. The models will then be used for predicting the outcome of TPS tests and selected benchmark and sub-element tests. Predictions will be compared with experimental measurements. The proposed product is a comprehensive design and life prediction methodology and associate software for its implementation, and design and fabrication of an improved TPS panel.
