Abstract
This paper investigates dynamic viscoelastic properties of magnetorheological (MR) grease with different fractions of plate-like Carbonyl Iron (CI) particles (MRGP). The plate-like CI particles were prepared through milling process. Subsequently, three types of MRGP was developed by dispersing 30 to 70 wt% of plate-like CI particles into grease using mechanical stirrer. The rheological test was performed using oscillatory shear rheometer under flux density influence of 0 to 0.7T and strain amplitude ranging from 0.001 to 10% at constant temperature of 25°C. The experimental results show that the storage and loss moduli of the MRGP is dependent on the fractions of the plate-like CI particles. The enhancement in the MR effect in the plate-like CI particles based MR grease is observed due to the anisotropy shape which leads to the strong inter-particle configuration and chain formations.
