Abstract
In this study, the mechanical properties of eight new porous structures were investigated. These structures are based on triply periodic surfaces derived from zeolite frameworks AWW, CGF, HEU, NPT, FRA, IFY, LTL and TSC; the TPSs obtained from the last four frameworks were found to be new minimal. Samples of TSC-based porous structures were made of polyamide using 3D printing methods and their mechanical properties (loading curves, compression modulus, shear modulus, Poisson’s ratios, and yield strengths) were experimentally and numerically studied. Numerically calculated mechanical properties were found to be in good agreement with the experimental results. We revealed dependences of the mechanical characteristics on the relative density of the material and estimated mechanical properties of porous structures obtained from other seven zeolites. The results obtained enable one to choose porous materials that are the most suitable in terms of their mechanical properties for various engineering applications.
