摘要

This work reported a novel flax-fibre-weaves (FFWs) incorporated magnetorheological elastomer (MRE), whose shear properties, compressive properties, tensile properties, and electrical performance were critically increased by the FFWs. In comparison to the pure MRE, the plastic deformation of the FFW-MRE was smaller and it absorbed more energy under the quasi-static compression and tension. With increasing of the FFW from 1 to 2 and 3 layers, the tensile strength of the MRE increased by 500%, 1300% and 3200% approximately. Because the carbonyl iron particles can form chain-like aggregation structure along the fibre directions, the conductivity of the FFW-MRE showed a typical anisotropic characteristic and it was sensitive to the external stimulus. When the compressive direction was parallel to the fibre weaves, the resistance of the FFW-MRE reduced to 2.7 k Omega, which was only 1/71 of the pure MRE. A possible mechanism was proposed to investigate in detail mechanical and electrical properties of the FFW-MRE. This method provides an economical, effective and environmentally friendly way to improve shear properties, compressive properties, tensile properties and conductivity of MREs.
