| Summary: |
Magnetorheological materials are a type of smart material whose rheological
properties can be manipulated within the presence of magnetic field.
Magnetorheological Elastomers (MRE) and MR Fluids (MRF) are examples of
materials under this class. Recently, MRF has been found to be not as reliable as
expected with issues of fluid sedimentation, leakage, oxidation, and hard cake effect.
This led to the re-emergence of MRE which does not possess the issues faced in MRF.
MRE is a type of smart composite material comprised of an elastomer-based matrix,
magnetic particles, and additives. To make MRE a viable alternative to MRF, MRE
used solid matrix elastomer which can prevent all the issues that faced by MRF and
the properties of magnetic particles such as low remnant, and high saturation
magnetization make the MR effect in the rheological part is high. In order to possess
those qualities, the magnetic particles must disperse efficiently throughout the matrix
of the MRE |
