INVESTIGATION OF MECHANICAL PROPERTIES OF MAGNETO-RHEOLOGICAL ETHYLENE PROPYLENE DIENE MONOMER AND NATURAL RUBBER TYPE SYNTHETIC RUBBERS FOR BOTH ISOTROPIC AND ANISOTROPIC SITUATIONS

Magneto-rheological (MR) materials are in a smart material class that has the rheological properties to be quickly and reversibly controlled with the external magnetic field applications. Considering the technological developments the rubber-like smart materials has had a more functional usage area with magneto-rheological effect. This study investigates the axial mechanical properties of magneto-rheological Ethylene Propylene Diene Monomer (EPDM) and Natural Rubber (NR) type synthetic rubbers for isotropic and anisotropic situations. Also, these composite materials were built by means of hot press systems as either isotropic or anisotropic using magnetic field application after addition of ferromagnetic powders. The influence of magnetic field was investigated. In this study, NR rubber was found to be more susceptible in terms of smart material properties unlike EPDM synthetic rubber.
