Abstract
The magneto-rheological effects in iron-elastomer composites (IEC) were investigated by
simulation, surface topography, and 3D representation. The simulated behavior of magneto-rheological
elastomeric composites in the presence of an external magnetic field was determined and the influence
of magnetic intensity on the isotropic distribution of iron filler particles in IECs was investigated.
The magnetic intensity distribution was analyzed from the edge of the surface towards the center of
the IEC. The samples were characterized for microstructural images after experimental tests using both
micro-computed tomography (µCT) and scanning electron microscopy (SEM). The adhesion of filler
particles within the matrix of the magneto-rheological elastomer (MRE) composite and their distributions
were also investigated. µCT showed the overall 3D representation of IEC and the inner distribution of
filler particles revealed the presence of some porosity which may be due to bubbles and voids in the
matrix of the composite. Finally, a mechanism was established governing particle–particle interactions on
the basis of dipole–dipole interactions.
