Abstract

In this study as treating to filter silance coupling agent (KM-6030 improving coupling strength between matrix resin (bisphenole-A type epoxy resin) and filler (SiO2), breakdown strength was investigated on cases applying DC voltage to specimen. In the case on DC voltage, breakdown strength was improved bout 12.73% and 10.77% in specimen of 5[wt%] and 50[wt%] of filler content of 10 of epoxy. Therefore, it was investigate the effect that concentration of coupling agent and content of filler was influential on breakdown strength of epoxy resin.
