Abstract

In this report, the post-curing and chemical aging ratio of propellants are described according to several aluminum contents. Under the same curing conditions, it was confirmed that the post-curing period of propellant having the aluminum content of 18 wt% was longer than the propellant having the 2 wt% of aluminum. On the other hand, in the chemical aging ratio analysis including post-curing, the propellant having the 18 wt% of aluminum was confirmed that the chemical aging proceeds slowly compared to the propellant having an aluminum content of 2 wt%.

본 논문은 알루미늄 함량 변화에 따른 추진제의 후경화에 대한 영향성, 화학적 노화도에 관하여 기술하였다. 동일 경화조건에서 알루미늄 함량이 18 wt%인 추진제가 2 wt%인 추진제 대비 후경화 기간이 길어지는 것으로 확인하였다. 반면 후경화가 포함된 화학적 노화도 분석에서는 알루미늄 함량이 18 wt%인 추진제가 2 wt%인 추진제 대비 화학적 노화가 천천히 진행되는 것을 확인하였다.
