Abstract

The paper discusses generalized characteristics of porous materials such as permeability, structure matricity, and pore tortuosity. The permeability factor for different materials (powder, fiber, foamed) is independent of porosity but is determined by the pore structure. The matricity and tortuosity substantially decrease with increasing porosity.
