Development Mechanical Characteristic of Magneto-Rheological (MR) Fluid by Adding Graphene Oxide

Abstract

In this paper, mechanical properties of magneto-rheol ogical(MR) fluid is compared with MR fluid which is added by graphene. We mix the MR fluid with graphene oxide (GO) by 0.33% mass fractions (G33). Adding the graphene into MR fluid has an effect on the viscosity. Furthermore, MR fluid largely changed the magnetic characteristics when the magnetic field is generated. The G33 increases the shear stress on same condition due to the GO. The response time of MR fluid and G33 are similar. However shear stress of G33 is bigger than MR fluid itself and saturation time is much faster. The presented results demonstrate advantage of adding the GO into MR fluid.
