Fabrication and characterization of magnetorheological elastomer with carbon black

Abstract

In this study, the isotropic magnetorheological elastomer samples are fabricated with and without addition of carbon blacks into the silicon rubber matrix and carbonyl iron particles in the absence of magnetic field. Microscopic and morphological analyses, thermo-gravimetric analysis, MH measurements, thermomechanical analysis, dynamic mechanical analysis, tensile test and magnetorheological test of magnetorheological elastomers are performed to characterize the fabricated magnetorheological elastomers. The experimental results demonstrate that the addition of carbon black improves the mechanical properties of the magnetorheological elastomer. The fabricated magnetorheological elastomers can be used in applications such as adaptive tuned vibration absorbers and vibration reduction in sandwich structures.
