摘　　要：研究了碳相含量对原位合成的碳／陶复合材料（Ｃ－ＳｉＣ－ＴｉＣ－ＴｉＢ２）的结构和性能的影响。结果表明：随着碳含量的增加，材料的抗弯强度下降。材料的烧结温度应随着碳含量增加相应的提高。Effects of the content of carbon on the structure and properties of carbon/ceramic composite prepared by in-situ synthesis were studied.It is found that the bending strength of the composite decreases with the increase of carbon c ontent.The sintering temperature of the composite should be higher to obtain a dense carbon/ceramic composites when the carbon content increases.

关 键 词：碳相含量 结构 力学性能 碳 陶瓷 复合陶瓷
