Fig. 7 — Properties of square-tessellated compliant rolling-contact architected materials (CRAMs) made of Teflon. a Parameters that define the geometry of square-tessellated CRAMs. b Performance regions for the compressive and tensile Young’s modulus versus density and c shear modulus versus density achieved by such CRAMs. Extreme CRAM examples are provided from along the boundaries of these regions. d, e The same performance regions plotted on Ashby plots to compare the properties of square-tessellated CRAMs made of Teflon with other common materials
