Micro and nanoshungites - perspective mineral fillers for rubber composites used in the tires

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 20°C) and their temperature dependences (from -50 to +100°C) were constructed.
