摘要: This study focuses on the magnetorheology and sensing capability of graphite based Magnetorheological Elastomers (Gr MREs). By introducing (Gr) to conventional MREs, Gr MREs are derived. The anisotropic sample with 20% weight fraction was selected be compared MREs. microstructures were observed. Both steady state tests dynamic conducted rheological properties samples. For tests, effects strain amplitude, frequency both storage modulus loss measured. capability, resistance under different magnetic fields external loadings is measured a multi-meter. Either higher field or more loading results in increment. Based an ideal assumption perfect chain structure, mathematical model proposed investigate relationship between MRE loadings. In this model, current flowing through structure consists tunnel conductivity current, which depends modelling parameters identified reconstructed from comparison experimental results. indicates that prediction agree favourably well.
