Abstract A study of the mechanical behavior of elastomeric nanocomposites with a styrene-butadiene rubber matrix and filler in the form of single- wall nanotubes TUBALL ™ (made by OCSiAl) has been carried out. Materials filled by N -330 grade Carbon Black as a nanofiller was used for comparison. Studies have shown that the introduction of a small amount of nanotubes (7 phr) into styrene-butadiene rubber significantly affects the viscoelastic properties of the material, the softening effect and the growth of residual strain. In addition, the material becomes substantially anisotropic during the milling process. The rigidity of the material in one direction is many times higher than the rigidity in the perpendicular direction © 2022 The Authors. Published by ELSEVIER B.V.

Keywords: Filled rubbers; nanofillers; mechanical properties; nanotubes. 1. Introduction Research on filled elastomers has been going on for many years [1]. Despite this, there are still many unanswered questions in this area. In particular, many questions arise around the interaction of filler particles and polymer matrix [2]. The fact is that different filler particles change the mechanical properties of the matrix in different ways. Without careful research it is not clear what physical and chemical processes are behind this. Often, researchers limit themselves by mechanical testing without going into the physical mechanisms that determine the behavior of 15th International Conference on Mechanics, Resource and Diagnostics of Materials and Stru tures Anisotropic properties of styrene-butadiene rubber filled with single-wall nanotubes A.L.
