Failure Criteria for Carbon-Carbon Applicable to Contoured Woven ITE Materials

Abstract:

This project will develop an analytical model capable of predicting failure of carbon-carbon
(C-C) materials. The model will build upon the firm's in-house C-C analysis codes
and will develop demonstrated capability to predict failure of C-C composites. In
particular, methods for analyzing C-C materials such as the contoured weave designs
being developed for application to NASA's Advanced Solid Rocket Motor will be developed.
Verification of the model's predictive capability will be accomplished through correlation
of existing C-C experimental data.
The analytical method developed under this effort will yield the capability of predicting
failure in C-C materials under thermal stresses induced in service conditions. The
resulting failure criteria will be useful for predicting the margins of safety for
all future C-C ITE materials.
