Comparison of 3D Printed Conventional and Auxetic Composite Structures Under Quasi-Static Compression for Severe Loading Applications

Research output: Contribution to conferencePaperpeer-review

Abstract

This study investigates the energy absorption behaviour of various non-auxetic and auxetic unit cells under quasi-static compression. Four cellular structures with identical relative volume were designed and additively manufactured using a composite 3D printing technique. Compressive results conclude that the auxetic anti-tetra-chiral structure provides superior energy absorption compared with the other structures tested. This therefore promotes the use of auxetic structures as sandwich panel cores under severe loading scenarios.
