摘要
The oxidation behaviors in stationary air of C/C-SiC gradient matrix composites and C/C composites were compared with each other. The results show that the oxidation threshold of C-SiC materials increases with the amount of SiC particles in the codeposition matrix. The oxidation rate of C/C-SiC gradient matrix composites is significantly lower than that of C/C material. The micro-oxidation process was observed by SEM.
