Abstract The results of experimental studies of hyperelastic and relaxation properties of polymer composites with elastomer matrix based on hydrogenated nitrile-butadiene rubber filled with technical carbon particles in the temperature range 20−125°C are presented. The characteristic experimental strain curves of materials in extension at a constant strain rate and the stress relaxation curves in materials at various tensile strain levels are given. A possible version of constitutive relations for describing some specific features of mechanical behavior of the considered materials under finite strains is considered. The obtained experimental data are used to verify the proposed constitutive relations experimentally. It is shown that the temperature-time analogy permits one to use the obtained constitutive relations to analyze nonmonotone variations in the relaxation properties of the considered materials as the temperature increases in the range under study.
