- Received Date: 2009-08-12
Abstract: The fabrication of magnetorheological (MR) elastomers was studied by two vulcanization methods, including heat vulcanization (HV) and radiation vulcanization (RV), were em-ployed to fabricate MRE samples. The dynamical mechanical properties were characterized by using a dynamic mechanic analyzer. In particular, both the MR effect and its durability were investigated.The experimental results showed that RV samples have large magneto-induced modulus,large zero-field modulus,and good durability property of MR effect.To explain these results,cubic deformation and plasticizer migration were analyzed. Large magneto-induced modulus of RV sample results from cubic deformation during vulcaniza-tion process. And the plasticizer migration results in better durability of MR effect.
