Abstract

Auxetic structures present a viable method of enhancing the in-plane compression characteristics of honeycomb lattices. Here, hexagonal and re-entrant lattices have been compared under quasi-static compression. Given the inherent complexity of manufacturing an auxetic structure, 3D printing has been employed for specimen fabrication. Fibre reinforcements of Carbon Fibre and Fibreglass have been included in the vertical cell walls to provide stiffness in the direction parallel to loading. These reinforced specimens were then compared to a non-reinforced set. Specific energy absorption was found to improve when using the auxetic lattices. By reinforcing the structural walls, an increase in energy absorption was observed across all specimens, with the greatest enhancement offered by Carbon Fibre. Through the use of auxetic re-entrant structures, the in-plane compressive characteristics of honeycomb architectures may be improved. Â© 2019 International Committee on Composite Materials.
