Nowadays honeycomb core sandwich panel (hereafter, HSP for brevity) is widely used in various structures, such as inner and outer packages of aircraft. HSP is the composite structural material which consists of two face sheets and honeycomb core. Because of high compressive strength due to the buckling of the core, HSP has advantages such as high rigidity and high-performance impact absorption ability. Compressive strength of double wall which is the bonded part in honeycomb core is higher than the single wall, because of the constraint by two cell walls that compose the double wall part. In this study, an influence of the number of laminated cell walls on compression properties of sandwich panel has been investigated for a development of new core structure. The static compression test was carried out by using five core models which metamorphose honeycomb core including the basic core model which consists of only single wall part. From the obtained results, the compressive properties of the core models were evaluated.
