| 摘 要： | 用热物性综合测试仪测定了不同热处理温度下Ｃ／Ｃ复合材料的导热系数，通过Ｘ射线衍射石墨化度的测定及晶粒尺寸计算，分析了材料的材质。进一步讨论了热处理温度、石墨化度与导热系数之间的关系。表明试样中存在性质不同的３个组元，随热处理温度的升高，平行于碳纤维长向的导热系数值从２２００℃的１４７Ｗ／ｍ·Ｋ升高到２８００℃的１８０Ｗ／ｍ·Ｋ左右，而垂直方向从相应的４９Ｗ／ｍ·Ｋ升高到７０Ｗ／ｍ·Ｋ。

| Abstract: | Thermal conductivity values of C/C composite were obtained with comprehensive measurement apparatus of thermal physical properties under different heat treatment temperatures. The material quality was analyzed through measurement of degree of graphitization with XRD and calculation of microcrystal sizes. Furthermore, the relationship among heat treatment temperature, degree of graphitization and thermal conductivity was discussed. |
