Crystallographic inspiration for lightweight cellular structures
Abstract
Components utilising cellular structures allow combinations of stiffness, strength and weight that are beyond what is possible with monolithic, dense materials. Recent advances in additive manufacturing enable the production of such components in a single process and allow highly ordered cellular structures to be created. Work continues to determine what the optimum cellular structure should be for any given situation. Crystallographically-inspired cellular (CIC) structures seek to utilise many decades of fundamental research into the properties of crystals to aid in the determination of optimised lightweight components. This research programme seeks to build on recent findings on elastic symmetry of periodic void structures to demonstrate the potential of CIC materials as a new class of cellular structures.
