Effect of the Processing Conditions on the Mechanical Properties of Urethane Magnetorheological Elastomers

摘要: The aim of the study was to develop an innovative processing method magnetorheological elastomers (MRE). This comprises optimization MRE structure in context their performance magnetic field. influence amount ferromagnetic particles and arrangement relation external field investigated. Urethane were manufactured using polyurethane gels, supplied by Dow Chemical Company. As carbonyl–iron powder with size from 6-9)m produced Fluka used. carbonyl iron varied 1.5 33.0 vol. %. Magnetic strengths used during fabrication 0.1 0.3 T. samples particle chains aligned or slopped at 45 degree long sample axis produced. To evaluate effect on properties a deflection measured. Samples placed parallel lines deflected prior application After tended straighten which measured displacement sensor. range 0-0.9 T has been applied. Also compression tests carried out without within strength experiment showed that increases stiffness material. have stress-strain curves course.
