플라즈마 표면개질에 따른 FRP의 자외선 열화특성에 관한 연구

초록

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 generation of plasma were oxygen atmosphere. 0.1torr of system pressure. 100w of discharge power. and 3minutes of discharge time. the decrease in surfae 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
