AUXHEX – A Kirigami inspired zero Poisson's ratio cellular structure
This work describes the development, manufacturing and testing of a zero Poisson’s ratio PEEK cellular structure (AuxHex) made using Kirigami-inspired techniques. The AuxHex hybrid cell pattern is a combination of cells with different shapes that interlock with each other. This principle can lead to graded honeycombs possessing, in different areas, synclastic as well as anticlastic behavior. The AuxHex samples produced have been tested for flatwise compression according to ASTM standards and the results are compared with a unit-cell-based analytical model.
