Magnetorheological elastomer (MRE) is a promising type of smart material, suitable for shock absorbers in tank engine mount systems. In order to improve the performance of the shock absorber, we improve the magnetorheological (MR) effect of the MREs and reduce its loss factor by enhancing the interaction force between the particles and the substrate. In this work, a novel carbon-coated iron material was prepared by heat treatment, and then carbon-coated iron ([email protected]) of different proportions was added to natural rubber to prepare MRE samples. The tensile strength and elongation at break of the MRE samples were tested by a universal electronic tension machine. The results indicated that better bonding strength between the particles and the matrix increased in tensile strength. The MR effect and the loss factor of the MRE samples were tested by a rheometer. The results demonstrated that the MR effect of MREs modified with [email protected] was significantly improved, and the loss factor of this kind of MRE decreased markedly.

磁流变弹性体 (MRE) 是一种很有前途的智能材料，适用于坦克发动机悬置系统中的减震器。为了提高减震器的性能，我们通过增强颗粒与基材之间的相互作用力来改善 MRE 的磁流变 (MR) 效应并降低其损耗因子。在这项工作中，通过热处理制备了一种新型的碳包覆铁材料，然后将不同比例的碳包覆铁（[email protected]）添加到天然橡胶中以制备 MRE 样品。MRE 样品的拉伸强度和断裂伸长率通过通用电子拉力机进行测试。结果表明，更好的颗粒与基体之间的结合强度增加了拉伸强度。MRE 样品的 MR 效应和损耗因子通过流变仪进行测试。结果表明，使用[email protected]修改的MRE的MR效果得到显着提高，并且该类MRE的损耗因子显着降低。
