Abstract

In this study, the viscosity of carbon black filled HTPB liner, mechanical properties and bonding force between propellant and liner were investigated. It is difficult to apply carbon black filled HTPB liner to the motor case in using a horizontal centrifugal casting because of its high viscosity. This problem is solved as a ageing premix at $60^{\circ}C$. The viscosity of premix is drastically decreased from 464 to 200 poise after 6days ageing.

본 연구에서는 HTPB에 보강제로 Carbon black이 충전된 라이너의 점도, 기계적 특성, 추진제와의 접착력을 고찰하였다. Carbon black이 충전된 라이너는 점도가 높아 수평원심 주조 방법으로 라이닝에 문제가 있었다. 이 문제점을 해결하기 위해 프리믹스를 $60^{\circ}C$에 6일 숙성시킴으로써, 점도 464 posie에서 200 posie로 감소시킬 수 있었다.
