Fiber reinforced epoxy nano-composites have replaced the conventional polymer composites for their inherent advantages. However, in the use of nano-composites for HV insulation, several challenges are faced in achieving a proper balance of electrical, thermal and mechanical characteristics. Improvements in the properties of the composites have been achieved by combination of nano and micron sized fillers. This paper considers the merits of combining micro and nano fillers in an epoxy matrix

Nano silica and nano alumina fillers have been combined with three micro-fillers namely Magnesium oxide, Calcium carbonate and ATH to form hybrid composites and their performance is compared with that of the base glass epoxy composite. The improvements in few electrical and mechanical properties have been discussed in this paper.
