No.9(2014)11.Influence of the structure of polyhedron sandwich-core panel on mechanical properties
Shunya Takahashi, Yasuhiro Nishikawa, Yujiro Abo
The structure of the sandwich core was improved in this study to develop a high rigidity sandwich core hard to peel off between the skin and core material. A sandwich core has been prepared by bonding the plates with polyhedron unlevel structure. Because the area for bonding is larger than that of honeycomb, the sandwich core is hard to peel off from the skin material. The bending test results show that, the panel using the sandwich core developed in this study has higher rigidity than the honeycomb panel. Results of the compressive test show that the developed sandwich core may have the shock absorbing performance.
