the introduction of fibers in the composite leads to a change of the structure, properties and manufacturing technology of the material. This paper presents method of calculation of the compositions disperse-reinforced sulfur materials. Presents formulas to determine the total surface of the filler particles and fibers; surface, number and volume of fibres; the reinforcement ratio; the volume fraction of the filler; mass of sulphur, filler, fibres and modifiers
