Abstract

Ballistic property of Heracron/phenol composites was evaluated as a function of polyurethane (PU) type and their loadings. First, prepregs of phenol and polyurethane were prepared by spray coating on Heracron fabric and then they were utilized to prepare composite by varying their ratio. Next, they were consolidated at $150^{\circ}C$ for 25 min at $150kg/cm^2$ pressure and then ballistic property was measured with 1.1 g FSP (22 cal). V50 was evaluated interms of polyurethane type and ratio of phenol/PU prepreg.

열경화성 및 열가소성 우레탄 수지 첨가에 따른 헤라크론/페놀수지 복합재료의 방탄성능 변화를 고찰하였다. 먼저 페놀 또는 우레탄 수지를 헤라크론 직조섬유에 스프레이 코팅하여 프리프레그를 제조하고, 이들의(페놀/우레탄) 비율을 변화시켜 16층의 복합재료를 $150^{\circ}C$에서 $150kg/cm^2$의 압력으로 25 min간 성형하여 제조하였다. 방탄성능은 1.1 g 모의파편탄(22 cal)으로 분석하였으며, 우레탄 수지의 종류 및 페놀/우레탄 프리프레그의 비율에 따른 V50 변화를 고찰하였다.
