Magnetorheological plastomer (MRP) is a new type of smart magneto-sensitive soft materials. Because of its outstanding magneto-controllable properties, the MRP is promising for noise and vibration reduction, acoustic absorption, magneto-responsive sensors, and etc. Based on the pre-research results, this proposal is aiming to develop high performance MRP and study its mechanical properties. Both the experimental and theoretical methods will be conducted so as to get the relative constitutive models for describing their mechanical behaviors. The typical analytical model for the microstructure-transformation of the MRP will be constructed to analyze the influence of the external magnetic field on the microstructures and this result must be much helpful for optimizing the pre-configuration process of magnetorheological elastomer, too. Moreover, several prototypes of the devices based on the MRP will be designed on this basis of its mechanical behavior and the relative fundamental scientific points will be focused. All the above researches can afford experimental and theoretical supports for both the development and applications of magnetorheological materials.
