Abstract

In this study, to improve the ballistic efficiency of very brilliant alumina-silica armor material, forming press and sintering temperature were changed. After physical/mechanical measurement, we measured ballistic properties about KE(Kinetic Energy, L/D=10.7, tungsten heavy alloy) and HEAT(High Explosive Anti-Tank, K215) projectiles and analyzed them. As a result, in $1235^{\circ}C$, it appeared the highest ballistic efficiency about HEAT and it improved $22\%$ ballistic efficiency, better than invented alumina-silica armor material before.

본 연구에서는 방탄물성이 매우 우수한 알루미나-실리카계 방탄재료(PL-8)의 방탄물성을 향상시키기 위해 성형압력 및 소결온도를 변화시켰다. 물리/기계적 물성을 측정 한 후 성형작약(HEAT)/운동에너지(KE)탄에 대한 방탄물성을 측정하여 분석하였다. 그 결과 소결온도 $1235^{\circ}C$에서 성형작약탄에 대한 방탄물성이 가장 높았으며 기 개발된 알루미나-실리카계 방탄재료 (PL-8)에 비해 $22\%$ 방탄물성이 향상되었다.
