Abstract

This study investigates the torsion modulus of elasticity in magnetorheological elastomers (MREs) composed of silicone rubber matrices and stabilized iron nanoparticle fillers. Isotropic and anisotropic samples were prepared using different filler pre-treatment methods and magnetic field orientations. A measurement system for testing the torsion modulus of elasticity for isotropic and anisotropic samples was developed. The results show that both particle dispersion and alignment significantly affect the mechanical properties. In particular, the torsion modulus increased in the presence of a magnetic field with transverse anisotropic samples exhibiting the most pronounced response. These findings highlight the potential of MREs for applications in adaptive mechanical systems such as tunable vibration dampers, soft robotic actuators or controllable stiffness components where mechanical properties can be dynamically adjusted using an external magnetic field.
