전기절연재료를 개발하기 위하여 에폭시-나노실리카-마이크로실리카 혼합 콤포지트 (ENMC)가 합성되어졌고 그리고 기계적 특성 가령 인장강도와 굴곡강도 그리고 AC절연파괴 강도가 연구되어졌다. 기계적 강도와 AC절연파괴 강도의 특성이 와이블 플롯에 관계한 스케일 파리미터와 형상파라미터가 분석되어졌다. 그들 인장강도와 굴곡강도, AC 절연파괴강도가 원형에폭시수지와 EMC이 ENMC에 비교되어졌다. 4 phr 나노실리카 첨가와 65 wt% 마이크로 실리카 혼합 콤포지트는 인장강도와 굴곡강도가 가장 높다는 것을 알 수 있었다. 인장강도는 원형에폭시 보다 더 29% 향상되었고 그리고 굴곡강도는 60.9% 향상되었다. 절연파괴강도에 있어서 EMC에 비하여 ENMC_4phr는 17%향상되었고, ENMC_5 phr는 15.8% 향상되었다.

In order to develop electrical insulation materials, epoxy-nanosilica-microsilica mixture composites (ENMC) was synthesized, and mechanical properties such as their tensile and flexural strength, and AC insulation breakdown strength were investigated. Properties of mechanical strength and AC insulation breakdown strength are analyzed as scale and shape parameter with respect to weibull plot. Their tensile and flexural strength, AC insulation breakdown strength were compared original epoxy or EMC to ENMC. The 4 phr nano-silica addition and the 65 wt% micron-silica mixture composite (ENMC) was found to have the highest tensile and flexural strength. In the tensile strength was improved 29%, and flexural strength was improved 60.9% higher than those of the original epoxy. In the insulation breakdown strength, ENMC_4 phr was improved 17% and ENMC_5 phr was improved 15.8% higher than those of the EMC.
