C/C复合材料的石墨化度反映了材料中碳结构与理想石墨晶体结构的接近程度，并且是影响其性能的一个重要结构参数。石墨化度P1是一种能够比较准确地表示碳材料石墨程度结构的参数。本文利用P1的基本模型，编制了相应的计算程序，通过X光衍射（XRD）分析，计算了不同热处理温度C/C复合材料石墨化度P1，结果表明它可以较好的表征C/C复合材料的石墨化程度。并进一步讨论了热处理温度（HTT）与石墨化度的关系。
The graphitization degree is one of the most important structural parameters of C/C composites. But it is difficult to be exactly measured for their multiformity. The probability for adjacent hexagonal layer planes in parallel to regular graphitic stacking (P1) is the most exact evaluation of the development of graphitic structure in carbon materials. The P1 of series of C/C composites in different heat-treated temperture (HTT) are obtained from computer computation according to the shape but not the position of of XRD peaks. The results show that P1 can characterize the graphitization degree of C/C composites satisfactorily.In addition, the relation between the garphitization degree of C/C composites and HTT was discussed in this paper.
