Physical-mechanical properties of rubber filled by mineral filler (micro and
nanoparticles of shungite) were studied experimentally. To date, shungite is one of the most
promising materials used in the tire industry as active reinforcing fillers. Experiments on
uniaxial tensile at break showed that input of this filler leads to a significant increase in rubber
strength. Investigation of thermo-viscoelastic properties of these materials using dynamo-mechanical
analyzer (DMA) were also carried out. As a result, the dynamic and
viscous modulus dependences on the frequency (at 20œC) and their temperature
dependences (from -50 to +100œC) were constructed.
