A Study on Mechanical and Electrical Properties at Interfaces Between Epoxy and ifs Molded Metal
초록
Epoxy compound has been used as insulation material in electrical equipment for a long time because of its excellent electrical, mechanical and chemical properties. Nowdays, becoming higher voltage system, the properties of interface between epoxy and metal insert become more important. The breakdown voltage of epoxy compound for electric material is variable according to the surface roughness of metal insert. Generally, with metal insert sanding, the adhesion strength is enhanced and the breakdown strength is reduced. But in this study, we knew that the adhesion strength became enhanced but the breakdown strength didn\`t reduced with metal insert sanding. So in this study sanding. So in this study, we suggest the optimum interface condition by adjusting the surface roughness.
