초록

본 연구에서는 다공성 심재를 갖는 샌드위치 복합재료의 압축해석을 수행하였다. 알루미늄 폼 및 허니컴 코어 샌드위치 복합재료의 유한요소모델은 솔리드 요소를 적용하였다. 알루미늄 폼 코어의 경우에는 유효등가손상모델을 적용하였다. 면내 압축해석에서 알루미늄 폼 및 허니컴 코어 샌드위치의 압축 최대하중이 비슷했다. 그러나 알루미늄 허니컴 코어 샌드위치의 하중 지지구간이 더 길었다. 면외 압축에서는 알루미늄 허니컴 코어 샌드위치의 압축 최대하중이 알루미늄 폼 코어 샌드위치보다 높게 나왔다. 시뮬레이션 해석을 통하여 샌드위치 복합재료의 압축 거동을 얻을 수 있었다.

In this study, compression analyses of sandwich composites with porous core were carried out. Finite element models of aluminum foam and honeycomb core sandwich composite material were applied solid element. In the case of aluminum foam core, valid equivalence damage model was applied. In the in-plane compression analysis, the maximum load of aluminum foam core sandwich was similar with that of aluminum honeycomb core sandwich. But in case of aluminum honeycomb core sandwich, the load support region becomes longer in comparison with aluminum foam core sandwich. In the out-plane compression analysis, compression maximum load of aluminum honeycomb core sandwich was higher than that of aluminum foam core sandwich. Through these Simulation analysis, obtains the behavior of sandwich composites.
