초록
극저온 추진제 탱크를 개발하는 과정에서 복합재와 알루미늄 라이너를 접합하기 위한 접착제의 선택은 탱크의 안전성과도 직결된 매우 중요한 문제이다. 따라서 적합한 극저온용 접착제를 선택하기 위해 3종류의 접착필름이 선정되었으며 극저온용으로 개발된 탄소섬유/에폭시와 라이너 재료로 사용되는 알루미늄으로 구성된 양면 겹치기 조인트 시편을 제작하였다. 제작된 시편을 극저온 환경챔버를 사용하여 상온과 150°C에서 인장실험을 수행하여 각 접착제의 접착강도를 비교하였으며 파손 특성을 분석하였다. 또한 양면 겹치기 조인트 시편의 각 구성재료의 온도에 따른 기계적 물성변화를 측정하였으며 이를 이용하여 ABAQUS를 통한 유한요소해석을 수행하여 양면 겹치기 조인트 시편의 인장시험결과를 분석하였다.
Abstract
In the development of a cryogenic propellant tank, the proper selection of adhesives to bond composite and metal liner is important for the safety of operation. In this study, 3 types of adhesives were tested for the ability to bond CFRP composites developed for cryogenic use and aluminum alloy (Al 6061-T6) for lining the tank using double-lap joint specimens. The double-lap joint specimens were tested inside an environmental chamber at room temperature and cryogenic temperature (-150°C) respectively to compare the bond strength of each adhesive and fracture characteristics. The material properties with temperature of component materials of double-lap joints were measured. In addition, ABAQUS was used for the purpose of analyzing the experimental results.
