| 摘 要： | 叙述了用Ｘ－射线衍射（ＸＲＤ）表征炭－石墨化度的来源，以及炭－石墨材料与炭／炭复合材料的不同点。在一定的实验基础和理论分析上，提出目前ＸＲＤ测试的Ｇ参数表征Ｃ／Ｃ复合材料的石墨化度时不完善，它只反映了Ｃ／Ｃ组分中石墨化度高的组分的石墨化性能。同时提出了两种Ｃ／Ｃ复合材料石墨化度表征的新方法，一是考虑衍射强度的Ｇ参数的修正公式；另一是利用激光拉曼光谱来表征。

| Abstract: | The commonly used Mering Maire graphitization factor(G) with the application of XRD d 002 value of carbon graphite materials is unsuitable for the characterization of multi components C/C composite,in which well graphitized component amounts less than a half portion of all composite.By means of experiments and theoretical analysis,we prove that G is unaccurate to characterize the graphitization degree of C/C composite.The parameter G characterizes the grapitization degree of only the best graphitized component of all C/C components.Two new characterization methods for C/C composites are presented in this paper,one is the revision of parameter G with diffraction intensity;the other is using laser Raman spectroscopy. |
