Abstract: The effect of additives on mechanical properties of rapid CVD oxidation ---resistant C/C composites was explored by orthogonal design test method. The optimal composition was determined. The experiment results show that the initial oxidizing temperature, flexural strength and flexural modulus of C/C composite manufactured by optimizing composition are 657℃, 254MPa and 49MPa respectively. The regular of effect of additives on mechanical properties of this kind material was analyzed.
