Abstract
In recent times, usage of Composite materials is one of the methods to achieve cost effectiveness of a product. In the current research it is intended to characterize a composite material for the usage in bumper reinforcement – automotive application. Materials chosen for the investigation are a natural fiber (JUTE), synthetic fiber (E - GLASS) and resin (EPOXY). Composites are casted by conventional hand lay-up technique cured at room temperature. Further tailored to required dimensions and finally tested for dynamic mechanical properties such as natural frequency by Fast Fourier Transform analyzer (FFT). It can be concluded that, as the percentage of jute increases and E-glass decreases for lower percentage of Epoxy the stiffness of composite decreases resulting in increased vibration levels. The tests are repeated for different composition of resin which also shows similar trend and change in the value of natural frequencies.
