Effect of Cell Wall Thicknesses on Compressive Properties of Double Layer Aluminum Honeycomb Core Sandwich Panels

The superior compressive property of double layer honeycomb core sandwich panel has been studied from compressive tests of double layer aluminum honeycomb core sandwich panel. In the previous paper, the effect of core height was reported. In this paper, the effect of cell wall thickness was clarified as follows : 1) The compressive strength of the laminated panel depended on the highest one in single layer panels that were an equivalent cell wall thickness and an equivalent core height to each layer of laminated panel respectively. 2) The absorption energy of the laminated panel was superior to the total absorption energy of single layer panels that were an equivalent cell wall thickness and an equivalent core height to each layer of laminated panel respectively. 3) The specific compressive strength and specific absorption energy of the laminated panel was inferior to those of single layer panel that was the higher cell wall thickness in the laminated panel and an equivalent core height to the total core height of laminated panel.
