Elaboration and Identification of the Physical Properties of Magnetorheological Elastomer

Magnetorheological elastomers are smart materials that have recently attracted considerable interest. Their physical properties vary significantly in presence of a magnetic field. This study examines these properties and proposes a new model for the design of systems using magnetorheological elastomers. First, a fabrication process for these materials is presented, and then their dynamic properties are studied under different magnetic field intensities and different filling rates by ferromagnetic particles. To control and ensure uniaxial orientation of the ferromagnetic particles, the magnetorheological elastomer samples at different filling rates were cured under a magnetic field via coils. A variation in shear moduli was observed with increasing volume fraction of ferromagnetic particles and applied magnetic field. Using these experimental results, the appropriate volume fraction of ferromagnetic particles, applied magnetic field, and design procedure can be proposed as guidelines for optimizing the development of future magnetorheological elastomers.
