Summary

A model for the oxidation of carbon fibers in a cracked C/SiC composite has been developed in order to better understand environmental/oxidation effects on the strength reduction and life of the composite. The physics based model simulates the oxidation of crack bridging carbon fibers across a 2-D plane within the composite. Oxygen concentrations and carbon consumption can be tracked throughout the 2-D plane with respect to time. The model will be compared to experimental results from stressed oxidation (stress rupture) tests conducted in an air environment. The amount of carbon consumed versus time and oxidation trends from the model will be compared to that of polished cross-sections taken from tested samples.
