Abstract

Isotropic and anisotropic silicone rubber-based magnetorheological (MR) elastomers with various concentrations of silicone oil were fabricated, and their dynamic viscoelastic properties were measured. The tested results showed that the silicone oil played an important role in the MR elastomers. The sample with a higher concentration of silicone oil had lower zero-field storage modulus and larger storage modulus increasing rate. For the MR elastomer without silicone oil, the anisotropic sample showed higher storage modulus increasing rate than its isotropic counterpart. However, for the MR elastomers with 15% weight fraction of silicone oil, the isotropic sample dominated in the storage modulus increasing rate.
