Abstract
Magnetorheological Elastomers or better known as MRE, is categorized as a smart material which changes its properties when subjected to magnetic field. However, there are still shortage on studies on this material such as on its behaviour and property under different conditions such as increasing of CIP and others. This experimental study is an inexpensive method to discover and research about the properties and behaviour of MRE under the influence of magnetic field, increasing percentage of CIP, and using the sandwich beam configuration. This experimental testing would use an FFT Analyzer, an impact hammer and accelerometer sensor as the main equipment. The main calculations of the experiment searches for the shear modulus of the MRE and also the loss factor of the MRE. The results are tabulated in tables and graphs to show the relationship of the shear modulus of MRE against the increasing percentage of CIP as well as the loss factor of the MRE against the increasing percentage of CIP in the MRE. Besides that, results are also plotted for the shear modulus against the strength of magnetic field. The graphs of loss factor against the increasing strength of the magnetic field are also plotted.
