Studies of elastomeric nanocomposites mechanical behavior under biaxial loading

Biaxial cyclic tests of elastomeric composites filled with granular nanoparticles (carbon black and detonation nanodiamonds), nanoplates (few-layer nanographene) and nanofibers (multi-walled carbon nanotubes) have been carried out. The experiments were carried out on Zwick/Roell's unique four-vector test stand using special fan-type cruciform specimens. Studies have shown that carbon nanotubes have the greatest influence on the change in the mechanical properties of a material during cyclic deformation in mutually perpendicular directions. It is they, due to their length and flexibility, that most effectively participate in the restructuring of the microstructure, thereby forming the macroscopic behavior of the material.
