Fig. 2: Assembly of segmented U-shape units into 2D honeycomb architecture.
From: Damage-tolerant material design motif derived from asymmetrical rotation
a Schematic of the assembly steps. b, c Segmented honeycomb 1 (SH1) b before and c after coating. d, e Segmented honeycomb 2 (SH2) d before and e after coating (for more images and size details of SH1 and SH2 refer to Supplementary Fig. 2, Supplementary Fig. 3 and Supplementary Table 2). f X-ray micro-computed tomography (micro-CT) image showing cement coating of SH1. g Magnified view of the part outlined in (f). h, i Cross-sections shown in (g) show the asymmetric coating of cement paste on two sides of the polymer scaffold due to surface tension and polymer curvature. Scale bar = 1 cm.
