Improved mechanical properties of magneto rheological elastomeric composite with isotropic iron filler distribution

Abstract

In this work, mechanical property of magneto rheological elastomeric (MREs) composite is investigated using iron as filler distribution. The MREs composite were fabricated using irregular shaped iron particles with size range varies from 50 -150 μm in matrix of elastomeric polymer. The matrix such as ZA22 was considered with 1:1 catalyst ratio as the binder with 30 Vol % of filler content. The fillers were incorporated within the matrix of elastomer using silicon oil as additive binder in the composite. The open circuit solenoid coil was designed as the magnetic circuit for magnetic flux intensity. Various magnetic field intensities were induced to observe the mechanical properties of the MREs composites. Hysteresis loss was observed in MRE samples due to dissipation of energy during compression of the composite material. Improved engineering strength of the MRE is observed on varying magnetic field of intensity and constant at 0.3 Tesla.
