Assessment of various additives in magnetorheogical-elastomer for impact applications

This study aims to determine the suitable additive materials for MRE for impact application. Magnetorheological (MR) is an intelligent, which its mechanical and rheological properties can be altered upon applying a magnetic field. MR can be formed as a fluid, a gel, or a solid-like elastomer. During the fabrication of MR, the matrix materials, magnetic particles, as wellas ratio, are set using either a room-temperature or a high-temperature vulcanization curing method. This study focuses on the magnetorheological elastomer, also known as MRE, on the impact application. Matrices such as rubber, magnetic particles, and other additives are used in the preparation, and the procedures for fabricating the MRE are explained. In addition, MRE properties with a varied current are discussed from the impact test data. The performance of MRE with additives of ferrite in the impact test is slightly better than zinc, copper, and aluminium, which is 5.73%, 7.03% and 9.37%. The result shows that ferrite is the most suitable material to be used as an additive in fabricating the MRE.
