Dynamic mechanical analysis of Magnetorheological Elastomer

Dynamic mechanical properties are the mechanical properties of materials as they are deformed under periodic forces. These properties can be expressed via dynamics modulus, the loss modulus and a mechanical damping or internal friction. This paper describes investigations on dynamic mechanical analysis of Magnetorheological Elastomer cured with and without magnetic field. Sylgard\´s 184 Silicone Elastomer has been used with 5 micron size iron particle. Viscoelastic properties such as storage modulus (E\´), loss modulus (E"), damping, were compared for with and without magnetic field curing.
