铁弹性复合材料是一种具有独特性能的智能材料，包括大的磁变形效应、强场增强的弹性模数和磁形状记忆。根据力学测试、直接显微镜观察和磁性测量，我们得出结论，所有这些效应都是由于聚合物基质中的磁性粒子在外加电场的作用下发生可逆运动而引起的。给出了外场作用下磁活性弹性体中颗粒结构模型的基本观点。
Ferroelastic composites are smart materials with unique properties including large magnetodeformational effects, strong field enhancement of the elastic modulus and magnetic shape memory. On the basis of mechanical tests, direct microscopy observations and magnetic measurements we conclude that all these effects are caused by reversible motion of the magnetic particles inside the polymeric matrix in response to an applied field. The basic points of a model accounting for particle structuring in a magnetoactive elastomer under an external field are presented.
