| 摘 要： | 研究了影响炭／炭复合材料导热系数的主要因素：炭纤维取向，热处理温度和CVD热解炭的结构，结果表明，在炭／炭复合材料中，影响炭／炭复合材料导热系数的主要因素是CVD热解炭结构；以RL结构为主的CVD热解炭，导热系数高，热处理温度对材料导热系数的影响不及CVD热解炭的微观结构对其的影响。

| Abstract: | This paper focuses on the main factors on heat conductivity for carbon carbon composites: the orientation of the carbon fiber; the temperature of heat treatment and the microstructure of the pyrolytic carbon matrix. The results show that it is the CVD pyrolytic carbon that determines the heat conductivity of carbon carbon composites, and the effect of heat treatment temperature is limited. The results also show that the CVD pyrolytic carbon that has high concentration of RL has high heat conductivity. |
