Abstract

Nowadays roll core sandwich panels (RSPs) have been widely used in various structures, and thus, to identify the bending properties of RSPs is significant. The present paper aims to investigate the bending properties of RSPs by three-point bending tests. The study clarified the effects of core height, direction of roll core, and the position of applied load on the bending properties. The study also found that the RSPs were more useful for mobile and other types of structures, compared with the conventional honeycomb sandwich panels (HSPs) that are widely used now. Futhermore, theoretical shear moduli were obtained with Gibson's method, taking into account the anisotropy. The estimated displacements where the theoretical shear moduli were used coincided well with the results of the bending test for each direction.
