A STUDY ON THE PARAMETERS THAT INFLUENCE THE PERFORMANCE OF SANDWICH PANELS WITH CHIRAL TOPOLOGY CORES

Abstract

The sandwich plates can be ideal components for large and lightweight structures with increased strength, stiffness and stability. The use of cores with chiral cellular geometry will lead to the development of structural components with superior elastic and impact resilient properties. This paper proposes the design of lightweight sandwich panels with aluminum skins and a core made with a chiral geometry network having circular nodes. As a reference construction, the panel with the skins joined only by means of circular bushes(without supplementary stiffeners)is considered. Finite element analyses (FEAs)are undertaken in order to haracterize the behaviour of the considered panels as having supported edges, and loaded under lateral pressure.
