Abstract

The paper presents the results of determining the permeability coefficient for a system consisting of a dispersed filler and an oligomeric binder. Regolith was used as the dispersed material, for which the composition, size, and geometric shapes of its particles were determined. An oligomeric organosilicon material with a specified viscosity and density was used as the binder. A model of the porous structure of the dispersed material was developed, taking into account the shape and size of its particles. Comsol software with The Laminar Two-Phase Flow interface was used to calculate the permeability coefficient. The simulation was conducted at a temperature of +170°C, which corresponds to lunar day conditions. It has been found that for the model under consideration, with binder injection without additional pressure, the porosity of the composite material is 4.5%.
