This study presents static and dynamic characterization of nanowire-based magnetorheological elastomer (MRE) composites. MRE composites were synthesized using a silicone rubber filled with magnetizable particles. Fe and Co particles of varying weight fraction (10, 30, and 50 wt%) were dispersed in the elastomeric matrix. To assess particle morphology, nanowire-based MRE composites were compared with spherical microparticlebased MRE composites. Under static and sinusoidal compressive loads, the field-dependent properties of the MRE composites such as static and dynamic stiffness, elastic modulus, yield stress, and equivalent damping were measured using a modified material testing machine. To investigate particle alignment effects in nanowire-based MRE composites, samples were cured in the presence of a magnetic field (aligned nanowires) and in the absence of a field (unaligned nanowires).
