In this research,a series of hollow glass powder(HGP)reinforced magnetorheological plastomers(MRPs)were prepared to improve the impact resistance of the materials,and the dynamic compressive prop-erties of MRPs under high strain rate were investigated by using a split Hopkinson pressure bar(SHPB)system equipped with a customized magnetic device.Experimental results showed the HGPs greatly en-hanced the yield stresses of the MRPs.Especially,for MRPs with 9 vol.％carbonyl iron powders(CIPs),the magnetic-induced yield stress increased from 7.3 MPa to 17.1 MPa(134％increased)by adding 18 vol.％HGPs.The particle structures in MRPs were further simulated and the corresponding intergranular stress was calculated to study the enhancement effect of HGPs.The simulated results showed that more com-pact structures were formed with the excluded volume caused by secondary HGPs,so the yield stresses of the MRPs increased under a magnetic field.However,when the mass ratio of HGP to CIP was larger than 0.67,HGPs would hinder the formation of chain-like structures and reduce the magneto-mechanical properties.As a result,the replacing of CIPs by HGPs was proven to be an excellent strategy to improve the dynamic properties of MRPs.
