Abstract
Magnetorheological elastomers (MREs) are known to be smart composite materials able to storing and dissipating part of the energy when subjected to external excitation (magnetic field, temperature, frequency). In this paper, anisotropic magnetorheological elastomers containing 20, 30, and 40% of the micrometric iron particles MRE prepared. The magnetorheological characteristics such as, storage modulus, loss modulus and loss factor MRE measured by dynamic mechanical analysis (DMA) over a range of frequencies (0.01 to 100 Hz), strain amplitudes (0.01 to 20%) and temperatures (0 to 100°C). The magnetorheological elastomer during dynamic mechanical characterization is subjected to a constant magnetic field intensity value of 0.2 T. Increasing the excitation frequency also increases the magnetomechanical properties of the MRE. The temperature has a reversible effect with the frequency, we see that when we increase the temperature, the magnetomechanical properties of the MRE decrease. The experimental results precisely showed the variation of the dynamic moduli (storage modulus, loss modulus and shear loss factor) of the anisotropic MRE loaded with 20, 30, and 40% ferromagnetic particles as a function of the parameters of influence such as: frequency and temperature.
