摘　　要：用XRD多重分离软件分别对不同热处理温度下C／C复合材料进行衍射分峰处理，得出该材料由三种不同组元构成，即树脂炭、炭纤维和热解炭，并求出各组元的石墨化度值及所占比例，进而得到试样的加权平均石墨化度。用光学显微镜对试样表面进行分析证明了三种组元的存在，讨论了热处理温度与石墨化度的关系。The carbon-carbon composites obtained from different heat treatment tempertures are analyzed with XRD multi-separation software. the results show that the composites are composed of three different components. i. e. resin carbon. fibre and pyrolytic carbon and with its values of degree of graphitization and proportion calculated which further lead to the weighted averages value. The existance of three components is verified by optical micrography and the relationship between the degree of gratiphization and heat treatment temperature are discussed.
