| Summary: | Magnetorheological elastomer (MRE) is widely known as the class of smart materials which contained micron-sized ferromagnetic particles that can reversibly tune the mechanical properties of damping and stiffness coefficient respectively in the presence of magnetic field. However, the current MR technology of MRE is yet to provide any significant result for the fully utilisation of the said materials peak potential in the current industries. This thesis is concerning the investigation of the performance of MRE under different composition of materials selected differently from past studies to check on its stiffness and damping variability simultaneously. To prove the peak performance behaviour of MRE, this experiment is conducted with the fabrication process of the MRE, which is done in an orderly manner. The samples were tested on the static compression test mode in order to compare the static behaviour of a variety composition of the materials selected such as the ferromagnetic materials and the elastomer itself. To this end, five different samples are fabricated in isotropic and anisotropic method to compare the performance that will be affected by the presence of magnetic field during the curing process. The static tests are conducted so that the samples were compressed up to its 20% strain rate depending on the size of the samples. The ferromagnetic particles used for this experiment is Carbonyl-iron Particle. The magnetic field will be supplied by applying the neodymium permanent magnets with strength up to 500 mT. The result reported in this thesis is from the static compression test and the flaw checking such as the porosity and cracks to get a better understanding of the characterization and performance of the MRE samples. The results observe in this experiment is crucial to further improve the future application of MRE technologies in industries. |
