초록

For the purpose of practical use of epoxy composite materials, it has been widely known that adding filler is an indispensable condition for cost-effectiveness and reinforcement of mechanical strength. However, dielectric strength of insulators made of epoxy composites rapidly decreases due to interfaces between the epoxy resin and filler particles. In this paper, it is investigated that the electrical properties of epoxy resins as the function of nano-$SiO_2$ content. We obtained that breakdown voltage of 0.4[wt%] specimens is higher than the other $SiO_2$ content.
