Tribological and Viscoelastic Behaviour of Carbon Black Filled Rubber

Abstract

The paper describes a complex experimental research of tribological and mechanical properties of styrene-butadiene-rubber (SBR) filled with carbon black. Tribological properties of SBR rubber material are investigated experimentally using a home made device of ball-on-disc type. The response of SBR in sliding friction depends on sliding speed and on the loading force. The rate-dependent behaviour of carbon-black filled rubber is investigated in tensile tests with different loading rates and in relaxation tests. The viscosity-induced rate-dependent effects are described. The storage and loss moduli and phase angle δ dependency on different amplitudes and frequencies are determined by strain controlled dynamical mechanical analysis. The temperature dependence of dynamic and tribological behaviour of SBR is also investigated.
