Fig. 1: Configurations of TPMS shellular pressure vessels.
From: A micro-architectured material as a pressure vessel for green mobility
a P-surface as a TPMS that sections a cube-like space into two sub-volumes bounded by the blue-shaded and the orange-shaded surfaces. Examples of high-pressure resistant structures: b a tubular truss and c, a matrix of spheres connected with tubes. Unit cells, single-chambered, and double-chambered shellular pressure vessels of three types of TPMSs, d, P- surface, e, D-surface, and f, F-RD-surface.
