Abstract

Learning from natural materials, such as nacre, bone and spider silk, is an effective way to develop future high-performance composite materials and structures. In this work, a conceptual composite panel inspired by nacre from mollusc shells is proposed and simulated with different types of interlocked wavy laminates. The deformation and failure mechanisms of individual fibre and matrix (Vinylester resin) laminas in the proposed composite panel under dynamic loading are modelled and compared with their flat and traditional interlocked dog-bone-like counterparts. An effective polyurea backing layer, which was demonstrated to significantly reduce damage to the flat composite laminate in the au..
