Abstract
Abstract. The paper considers and summarizes the results of the investigation of the porous structure of a heat-insulating composite by the method of computer microscopy. Densitometric studies of the surface of a porous material indicate the formation around the pores of layers of material with altered characteristics, which is considered from the perspective of the determinant theory. An analysis of the radial distribution function of pore centers leads to the conclusion that structural ensembles are formed at the center of which there is a pore or a structure-forming particle. This hypothesis is confirmed by the study of the statistical characteristics of the Voronoi decomposition for pore centers, as well as the grouping of pores with a similar spatial orientation. The prescriptive and technological management of the geometric characteristics of structural ensembles makes it possible to purposefully influence the performance properties of the material.
