ABSTRACT
The method of obtaining high-strength elastomeric composites based on the matrix of a copolymer of styrene butadiene (E-SBR, 30% styrene), filled with particles of mineral shungite, whose main components are carbon and silica, is proposed. As a result of the researches, it has been established that the most efficient method of regulating the properties of the considered composites is the use of nanoscale particles of shungite as a filler in combination with the surface modifier of 3-thiocyanatopropyl-triethoxysilane, providing a high degree of dispersion of the filler in the volume of the composite matrix. Based on FE modeling, it is shown that the effect of improving the mechanical properties of the composite is associated with the increase in the relative volume content of interphase zones of bound rubber with decreasing particle size.
