Abstract

In this study, impact behavior of aluminium and glass-fiber structure is studied under low impact velocity. Compression test is carried out to investigate the compressive strength of the specimens. The degree of damage is observed using microscopy and compared with the experimental analysis data. The maximum load capacity, impact strength and elastic energy of glass-fiber honeycomb sandwich panel are more than the aluminium honeycomb sandwich panel.

본 연구는 동일한 코어재를 가지는 알루미늄과 유리섬유의 하니컴 샌드위치 판넬의 저속 충격시 발생하는 충격 거동 및 압축 실험을 통하여 압축 강도와 압축 계수를 살펴본다. 저속 충격을 받는 하니컴의 충격 거동을 살펴보기 위하여 중량 낙하식 충격 시험을 실시하며, 충격을 가한 후 데이터 분석 및 현미경을 통하여 전형적인 충격파손모드와 손상정도를 비교 평가하였다. 동일한 충격에너지일 때 유리섬유 하니컴 샌드위치 판넬이 알루미늄 하니컴 샌드위치 판넬보다 최대 하중이 높고, 탄성 에너지가 크며, 충격 강도가 높은 것을 확인할 수 있었다.
