摘要
本研究用化学气相渗技术制备了四种Ｃ／ＳｉＣ复合材料：在ＣＨ３ＳｉＣｌ３＋Ｈ２（普通）＋Ａｒ（高纯）系统中制各了两种材料：材料Ａ为１Ｋ炭布层叠无热解炭界面层，材料Ｂ为１Ｋ炭布层叠有热解炭界面层；在ＣＨ３ＳｉＣｌ３＋Ｈ２（高纯）＋Ａｒ（高纯）系统中制备了另两种材料：材料Ｃ和材料Ｄ分别为１Ｋ、Ｔ３００炭布层叠有热解炭界面层．分别对其中每两种材料进行了相互比较，研究了骨架纤维、界面层及基体对整个复合材料性能的影响；通过控制上述三方面因素可以对Ｃ／ＳｉＣ复合材料的总体结构进行设计从而控制其材料最终性能。
Abstract:Four kinds of C/SiC composites were prepared by the chemical Vapor Infiltration technique. Material A,B are 1K carbon cloth. A(without pyrolitic carbon interfacial layer),B(with pyrolitic carbon interfacial layer are fabricated from CH3SiCl3+H2 (common purity) +Ar(high purity) system, C and D are 1K, T300 carbon cloth lay up (with pyrolitic carbon interfacial layer). C. D are fabricated from CH3 SiCl3+H2 (hith purity )+Ar (high purity) system. The influence of reinforcements, inter facial layers and matrices on the characteristics of C/SiC composites were investigated through comparison of the every. two kinds of composites among them. The appropriate control of above three factors may decide the characteristics of C/SiC composites.
