چکیده
This paper deals with the study on mechanical and magnetic properties of Magnetorheological Nanocomposites (MRNCs) based on room temperature vulcanized (RTV) silicone rubber and nano-sized carbonyl iron particles (CIPs). The five samples was prepared using ammonium bicarbonate (NH4HCO3), CIPs, silicone oils and silicone rubber. All samples were manufactured under isotropic condition and their microstructures was characterized by x-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). Porosity characteristics was measured and porosity image analysis was applied through ImageJ and Origin Pro Software. The mechanical tensile tests was conducted using Gotech tensile strength tester. The magnetic properties of porous MRNCs were practically determined using VSM test. Plateau stress induced by the applied magnetics fields and MR effects was determined. Upon successful fabrication of MRNCs, the samples deflections was measured against applied magnetic fields .The findings shows that porosity increase the flexibility and relative magnetic permeability of MRNCs and porous MRNCs will be the desired candidate for miniature and flexible actuators.
