In order to investigate the magnetic-induced friction properties of magneto-rheological elastomers, isotropic and anisotropic magneto-rheological elastomers are fabricated, tribological testing setup is built, and the friction experiment is carried out. The experimental results show that the isotropic magneto-rheological elastomer has a decreasing friction coefficient with magnetic field applied, which is also affected by particle volume fraction. The influence of magnetic field on friction coefficient of the anisotropic magneto-rheological elastomers is not monotonic. The experimental results also show that the friction coefficient of magneto-rheological elastomers decreases with the increase in load for both isotropic and anisotropic magneto-rheological elastomers in most circumstances. The volume fraction of carbonyl iron powders being around 10% is the best for magneto-rheological elastomers in tuning friction. The tunable range of friction could be as high as 25% under a magnetic field of 0.25 T. Ima...
