| 摘 要： | 提出了由本身材质提高碳／碳（简称Ｃ／Ｃ）复合材料抗氧化性能的新途径，即在坯体中添加陶瓷微粉与石墨粉的混合物，用快速化学气相沉积工艺制成Ｃ／Ｃ复合材料。结果表明：制备的材料不仅氧化失重率小、氧化起始点高，而且致密。确定了其优化配方。分析了这种材料的抗氧化机理。

| Abstract: | A new way of enhancement of oxidation resistant properties for C/C composites was put forward by material itself.The mixture of ceramic and graphit power is added in prepregs,and C/C composites are prepared by rapid chemical vapour.The results indicated that the weight loss of C/C composites prepared is not only small,and the initial oxidizing temperature is high,but also more compact.The oxidation resistant mechanism was analyzed.The optimization of C/C composites was determined. |
