Impact Property of Double Layer Honeycomb Core Sandwich Panel

When a local compression load is vertically applied on a face sheet of Honeycomb core sandwich panel (hereafter, HSP for brevity), a dent will be formed at relatively low force. Therefore, local compression tests of HSPs with different core height were carried out for a peripherally clamped specimen and a bottom face fixed specimen. From obtained results, the follows were summarized: 1) There was no effect of core height on strength. 2) Two peaks on load -displacement curve appeared for the peripherally clamped specimen. But, one peak appeared for a bottom face fixed specimen. 3) A peak load at first time for a peripherally clamped specimen was least for all. A peak load at second time for a peripherally clamped specimen was higher than that for a bottom face fixed specimen. 4) An Energy absorption for a peripherally clamped specimen was superior to that for a bottom face fixed specimen, because of a deflection observed for the only peripherally clamped specimen.

Effect of Cell Wall Thickness on Local Compression Fatigue Property of Honeycomb Core Sandwich Panel

Local compression fatigue properties of peripherally clamped HSP have been studied in consideration of usage condition as a floor panel. In this study, the effect of cell wall thickness on local compression fatigue of HSP was clarified. For that purpose, a series of fatigue test of HSP was carried out by changing the cell wall thickness, the thickness of face sheet contacted the indenter and the maximum load value. When the cell wall thickness was thin, the fracture pattern of face sheet contacted the indenter changed from the tensile type to shearing type with the increase in the thickness of face sheet contacted the indenter. In the transitional region between these two fracture types, the only dent without crack was observed on the face sheet contacted the indenter. On the other hand, when the cell wall thickness was thick, the shearing fracture around dent was observed instead of the dent type in the transitional region.This was because of the increase of buckling strength of cell wall which constrained the formation of dent. This situation resulted in the increase in the shearing stress around the dent.

Effect of Core Height Ratio on Drop Weight Impact Properties of Double Layer Honeycomb Core Sandwich Panels

A honeycomb core sandwich panel (hereafter, HSP for brevity) is superior in impact absorption under whole surface compression, because of the buffer effect of core. However impact properties of HSP under local compression such as drop weight impact are affected by the plate as the face sheet in addition to the core layer. This research describes drop weight impact properties of double layer HSP which consists of two core layers and three plates. In order to build up the experimental database for design of double layer HSP, a series of drop weight tests was carried out by using double layer HSPs with the several ratios of the core heights. From obtained results, the follows were summarized: 1) Two or three peaks of the load appeared in the load-displacement curve. The peak loads were larger in sequence of their appearances.2) In the load-displacement curve until the last peak of the load, there are load increase regions by deep drawing of the plates and load equilibrium regions similar to plateau region under whole surface compression. 3) When the height of the upper layer core was lower, the absorption energy was larger in total. 4) An energy absorption model has been developed and verified for design of double layer HSP.
