研制了一种具有双向磁控模量的高阻尼磁流变弹性体。将NdFeB粒子填充到聚氨酯（PU）/环氧树脂（EP）互穿网络（IPN）结构中，制备了MRE。在永磁磁场中制备各向异性样品，并在1 T的电磁场中磁化。利用磁流变仪研究了磁流变液在外加磁场作用下的动态力学响应，并利用扫描电子显微镜（SEM）观察了磁流变液的形貌。试验结果表明，当测试场方向与试样磁化方向平行时，试样的剪切模量增大。另一方面，当取向与样品的磁化方向相反时，剪切模量减小。此外，这种PU/EP IPN基质MRE具有高阻尼性能，具有高损耗因子，并且可以通过施加磁场来控制。希望B的高阻尼性能和抗冲击能力能得到进一步的提高。
A high-damping magnetorheological elastomer (MRE) with bi-directional magnetic-control modulus is developed. This MRE was synthesized by filling NdFeB particles into polyurethane (PU)/ epoxy (EP) interpenetrating network (IPN) structure. The anisotropic samples were prepared in a permanent magnetic field and magnetized in an electromagnetic field of 1 T. Dynamic mechanical responses of the MRE to applied magnetic fields are investigated through magneto-rheometer, and morphology of MREs is observed via scanning electron microscope (SEM). Test result indicates that when the test field orientation is parallel to that of the sample's magnetization, the shear modulus of sample increases. On the other hand, when the orientation is opposite to that of the sample's magnetization, shear modulus decreases. In addition, this PU/EP IPN matrix based MRE has a high-damping property, with high loss factor and can be controlled by applying magnetic field. It is expected that the high damping property and the ability of b...
