Magnetorheological elastomers (MREs) have much interest in engineering applications. However, the mechanical properties of MREs are still under ongoing researches. This paper presents the results from tensile test, hardness and rebound test that were carried out in order to understand the mechanical properties of MRE with the influence of carbon black content. The addition of carbon black was varied with the amount of 20 pphr, 40 pphr and 60 pphr of carbon black. The development of the MRE composites was manufactured by following the conventional rubber compounding process. The optimum cure of each MRE composite was determined by using a Rheometer 100. The mechanical properties through tensile test were obtained by using an Instron Tensile Machine, meanwhile hardness and resilience were carried out by using Wallace Dead Load Hardness and Dunlop Tripsometer, respectively. The results of tensile strength were not consistent with the addition of carbon black. In meantime, hardness value increases as the carbon black increases. The decreasing pattern of MRE resilience could be observed when the carbon black content increases. © 2016 Penerbit UTM Press. All rights reserved.
