Abstract
Honeycomb sandwich structures are widely employed in the engineering field, due to their light weight, strong rigidity and high strength. In this study, the bending resistance performance of the honeycomb sandwich panel with ceramic tile face-sheet (short as ceramic sandwich) was investigated through three-point bending experiments. Their differences between the present ceramic sandwich and the conventional ones were reported and discussed in terms of deformation mode, load-deflection history and bending resistance. As the experiments turned out that differing from the conventional sandwich panel, the present ceramic one performs different collapse modes when undergoing 3-point bending load. The results demonstrated that the bending behavior of the present ceramic sandwich was largely promoted due to the ceramic tile face-sheet. Besides, the mechanical influence of the ceramic tile face-sheet and the cell edge length of honeycomb core were determined. These achievements pave a way of designing composited superb bending resistant sandwich structures.
