Observations on Mechanics Properties of Stitched Foam-Core Sandwich by Flexural Testing

摘要

Stitched foam-core sandwich structure is a new light weight sandwich structure material. In this paper, flexural testing was performed. For comparison purposes, the stitched foam-core sandwich structure with different stitch density and the unstitched foam-core sandwich structure were tested. The experimental results show the maximum failure loads was decreased owing to stitch for the flexural testing. The bending stiffness increases for stitched foam-core sandwich structure.
