A Study on the Impact and Vibration acting on the Laminated Composite Honeycomb Core Type Sandwich Plate Structure

복합적층 하니콤 코어형 샌드위치 판구조물에 미치는 충격과 진동에 관한 연구

In this paper, we analyzed the laminated composite sandwich plate structure of honeycomb core with changing values of the designing parameters. As a result, in designing parameters of that, the more height and thickness of the laminated composite plate's core, the more increase of natural frequency. The laminated angle has the maximum value when the plate of honeycomb core is join to opposite direction. This paper shows that the natural frequency of CFRP is higher than that of GFRP, and also impact strength marks maximum value in case of antisymmetry than symmetry of core. Also it shows that the mode shapes are various along with the angle-ply of laminated composite plate.
