摘要

本研究采用等离子体技术对复合材料进行干界面处理。实验结果表明，等离子体产生时样品的最佳润湿性参数为氧气气氛、0.1 torr的系统压力、100 W的放电功率和3分钟的放电时间。电晕放电使带电样品的表面电位下降，表明随着紫外照射时间的增加，积累的电荷量减少，注入的电荷迅速减少。等离子体处理样品的表面电阻率和抗拉强度，较长的紫外线照射时间导致绝缘降低

The analysis of surface degradation mechanism on epoxy/glass fiber used for outdoor insulator

In this study, composite materials were put to dry interfacial treatment by use of plasma technology. It has been presented that the optimum parameters for the best wettability of the samples at the time of generation of plasma were oxygen atmosphere, 0.1 torr of system pressure, 100 W of discharge power, and 3 minutes of discharge time. The decrease in surface potential of charged samples by corona discharge indicates that the amount of accumulated electrical charges reduces and the charges that have been injected lessen rapidly when the duration of UV irradiation increases. The surface resistivity and the tensile strength of plasma treated samples, a longer UV irradiation time resulted in decreased insulation
