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 rice husk ash as a reinforcing filler, is proposed. During the conducted investigations, it was established that the most efficient method of regulating the strength properties of the composites considered is the use of nanodispersed particles of rice husk ash as a filler in combination with the bis[3-(triethoxysilyl)propyl]tetrasulfide (TESPT) coupling agent providing a good dispersion of the filler in the composite matrix. For a sample filled with nanodispersed products of rice husk ash with a TESPT coupling agent, the average strength value was obtained to be 18.5 MPa, which was achieved for the first time for elastomeric composites with products of processing rice husk as a filler. However, these results are lower in comparison with the strength level of composites filled with Zeosil 1165 MP (25 MPa) due to the greater functionalization of the particle surface of the latter.
