| 摘 要： | 以高纯石墨为对照材料,初步研究了热解碳基碳/碳复合材料的内耗行为,并根据实验结果提出了碳/碳复合材料的内耗机制:热滞弹性机制与静滞后型内耗机制。纤维/基体的界面内耗效应对碳/碳复合材料的内耗特性影响很大,它的存在使碳/碳复合材料产生了一些较为反常的内耗现象。

| Abstract: | Compared with high pure graphite, the internal friction characteristics of pyrolytic carbon matrix carbon carbon composites were studied in the present work. According to experimental results, two internal friction mechanisms are proposed: thermoelastic and static hysteresis mechanisms. The effects of interface between carbon fibers and carbon matrix play important roles on the internal friction characters of carbon carbon composites, which leads to some unique internal friction phenomena in carbon carbon composites. |
