| 摘 要： | 使用炭毡为增强体分别制备了热解炭基、树脂炭基、沥青炭基和热解炭/树脂炭双基体、树脂炭/沥青炭双基体C/C复合材料,比较研究了复合材料的电导率与不同先驱体含量的关系。结果表明,不同前驱体C/C复合材料电导率有较大的差异,热解炭基C/C复合材料的电导率是沥青炭基C/C复合材料和树脂炭基C/C复合材料电导率近3倍,热解炭和沥青炭双基体C/C复合材料的电导率符合简单并联混合法则,树脂炭和沥青炭双基体C/C复合材料的电导率随树脂炭质量分数的增加而减小。

| Abstract: | Pyrocarbon-matrix,resin-matrix,pitch-matrix C/C composite and pyrocarbon/pitch dual-matrix,resin/ pitch dual-matrix C/C composites were prepared respectively with needle-punched carbon felt as reinforcement.The relation was researched and compared between content of different precursor matrix and conductivity.The results showed that C/C composites with different precursor matrix exhibit a great difference on conductive properties,the conductivities of resin-matrix C/C composite and pitch-matrix C/C composite are three times bigger than that of pyrocarbon C/C composites.Pyrocarbon and pitch dual-matrix C/C composite conductivity accords with the simple parallel connection principle.Pitch and resin dual-matrix C/C composite conductivity is the linear function of the resin carbon mass percent. |
