Abstract
Based on the oxidation kinetics of C/SiC composites at 900o-1200oC in stress-oxidation environment, a non-uniform model of oxidation has been suggested in this paper. Combined with fiber notch model, Curtin’s strength model and BHE model, the non-uniform model is able to predict the failure time and residual strength of C/SiC composites accurately. Besides, the initial defects of the model (matrix coating crack and open porosity), the effects of coating were taken into account, and the fiber strength and broken ratio were analyzed. Furthermore, the effects of oxidation time, stress, temperature, Si C coating thickness and volume fraction of fiber on the failure time and residual strength were discussed, and the predicted results showed a good consistency with the experimental data.
