초록

주파수 변화에 따른 에폭시 복합체의 전기적 특성을 알아보기 위하여 온도 범위 $20[^{\circ}C]$, $100[^{\circ}C]$, $140[^{\circ}C]$, 주파수 범위 30[Hz]~3[MHz] 사에서 유전율 및 유전손실을 측정하였다. 저주파 영역에서 유전분산과 유전 손실이 나타나고 있음을 확인하였다. 또한 고온 영역에서는 충진제의 영향으로 유전율이 감소하는 것을 확인하였다.

In order to study electrical properties of epoxy composites with various frequency. To measure of dielectric characteristics have been performed over a frequency range from 30[Hz] to 3[MHz] and a temperature range of $20[^{\circ}C]$, $100[^{\circ}C]$, $140[^{\circ}C]$. We observed values of dielectric constant and dissipation of the epoxy composites with various frequency. We were observed dielectric loss and dispersion in low frequency region. Also, we observed to decrease of the dielectric constant due to the effects of filler in high temperature region.
