Design and fabrication of hybrid magneto rheological elastomeric angular mounts with iron nano particles

Abstract

The article mainly focused on the experimental characterization and validation of magneto rheological hybrid elastomers based on SI/PU and NR/PU was fabricated. For optimizing preparation conditions two MRE samples were prepared with Fe2O3 nano particles respectively. The MR effect was improved especially by modifying the SI/PU, NR/PU-rubber ratio and compatibility improvement between SI/PU and NR/PU rubber. The preparation conditions influences the bond between the MR effect and microstructure of MRE “magneto rheological elastomer” are discussed in detail. The obtained results confirm that MR elastomer has good MR effect than that of MR elastomers with pure Si/PU matrix with same testing conditions. The existed microstructure in the presence of PU matrix interpenetrating the peculiar former forms as indicated in SEM analysis. Finally the analysis indicates that the use of Fe2O3 nano particles would increase the bond strength between rubber matrix and particles. These experimental results were also verified by the SEM images.
