| 摘 要： | 本文研究了碳/环氧复合材料在拉伸和弯曲过程中试样电阻率随外力作用而变化情况,并建立了电阻与应变关系曲线。结果表明,实验过程中电阻变化能够反映材料受力和破坏情况的特性,因此可以将这一特性作为研究碳/环氧复合材料自诊断的基础。

| Abstract: | The resistance variation of carbon-epoxy composite during strain and flexural were studied on this paper,and the relation curve of the resistance with strain was drawn.Test results show that the resistance of samples can reflect the situation of strain and destroy,which can be a selfdiagnose fundamental technology with carbon-epoxy composite. |
