Experimental Modal Analysis Study on Graphene filled SBR

Rubbers are widely used in many engineering applications such as tubes, timing belt, tyre etc. Apart from its functional use, it can also be used as damping material in many applications in order to dampen the vibrations transmitted from one structure to other. The present research work focus on the development of CB filled SBR and Graphene filled SBR. Both rubber samples were investigated for its mechanical properties such as hardness and tensile strength. Experimental modal analysis was also done to examine the dynamic characteristics such as damping and natural frequency along with its mode shapes for the prepared samples and compared. It is observed from the results that the inclusion of graphene in SBR improved its vibration characteristics in addition to the improvement of mechanical properties.
