二層積層アルミハニカムサンドイッチパネルの圧縮特性に及ぼす積層コアそれぞれの高さの影響

The purpose of this study is to discuss compressive properties of double layer aluminum honeycomb core sandwich panels. At present, the single layer panel is used as the shock absorbing constructed material. If the double layer laminated panel is used instead of the single layer panel, the improvement of the shock absorption will be expected. For a design of the shock absorption, it is very important to make clear both the buckling strength and the buckling energy under the compressive load. Therefore, a series of compression tests were carried out using the laminated panel that changed the core height. As a result, the buckling strength of the laminated panel depended on the highest one in single layer panels that were an equivalent core height to each layer of the laminated panel respectively. Moreover, the buckling energy of the laminated panel was superior to that of single layer panel, when heights of both panels were equivalent.
