GSW0108 Effect of radius of curvature on bending properties of honeycomb sandwich curved panel

Abstract

Three point bending tests were carried out on honeycomb sandwich curved panels which were made from an aluminum alloy and had radii of curvatures of 200, 300 and 400mm. Major conclusions obtained in this study are summarized as follows: 1) A bending strength of curved panels was about 10% higher than that of a flat panel regardless of the radius of curvature. 2) A flexural rigidity of the curved panel was decreased with the decrease in the radius of curvature. 3) An effect of a deformation of core on the bending property of curved panel became small with the decrease in the radius of curvature.
