Summary

This paper describes activities which are directed towards the development of information, understanding, and methodologies which can be used to predict the remaining strength and life of continuous fiber ceramic composite (CFCC) components, for the purpose of improving the static and dynamic performance of such material systems. The Materials Response Group has created the first (“alphaO”) version of a simulation code that combines basic property and performance data and understandings being developed in the CFCC program to describe and predict the long-term durability and damage tolerance of those materials at operating temperatures and conditions. A preliminary example of application of the code to composite strength is also presented, with comparisons to data.
