| 摘要: |
| 通过研究材料的氧化前后质量的改变和强度减少及氧化前后微观结构的变化，研究了先驱体转化法制备的SiCf/Si-O-C复合材料的抗氧化、抗热震性能。结果表明SiCf/Si-O-C复合材料具有良好的抗氧化、抗热震性能。对所得材料微观结构进行了分析讨论，发现界面结构的变化是影响SiCf/Si-O-C复合材料抗氧化、抗热震性能的主要原因。 |

| Abstract: |
| Properties of anti-oxidation and anti-shock of silicon carbide fiber reinforced siliconoxycarbide(Si-O-C) composites were studied through comparing the changes of mass and flexural strength and those of microstructure. The results indicate that SiCf/Si-O-C composites have fairly excellent properties. The microstructure and properties of SiCf/Si-O-C composites were analyzed. It has been found that interface structure changes were mainly attributed to the reduction of mass and flexural strength properties. |
