Experimental Investigation of MR Effect to RTV Silicone Rubber-based Magneto-rheological Materials
Journal Title: Cumhuriyet Science journal - Year 2017, Vol 38, Issue 3
Abstract
Magneto-rheological Elastomers are smart materials whose properties can be altered reversibly and almost instantaneously by application of external magnetic fields. Silicone rubber species are used widely in the laboratory studies because of it is easy to prepare and cured at room temperature.In this study, MRE material was produced using three different types of silicone rubber and ferromagnetic powder which is sensitive to magnetic field. MRE materials are obtained as isotropic (homogenous) and anisotropy (aligned) state. Composite materials were tested in uniaxial compression testing machine with three different test procedures. In this way, the mechanical properties and the magneto-rheological effect of the materials were compared. As a result, under the magnetic field to 0.430 T with anisotropic Sorta Clear40 materials were found to increase in stress 30%, according to the pure state has been demonstrated that the rate of 50%. When the isotropic Sorta Clear40 and Vario40 materials were comparable, MR effect was revealed that the increases the rate of about 325% at strain to 5%. When selecting to optimum rubber types was reached the result should be used to materials the most appropriate to the material characteristics of engineering aspects.
