Glass and carbon fibre reinforced with epoxy matrix hybrid composite have to be prepare by hand-lay-up Damping in composites involves a variety of energy dissipation mechanisms that depend on vibrational parameters such as frequency and amplitude and these are studied with nondestructive evaluation. In fiber-reinforced polymers, the most important damping mechanisms have been studied by Y. Chen and R. F. Gibson [10]. Carbon fiber reinforced polymer composites (CFRPs) have increasingly gained importance among the scientific community as well as industry due to their high specific strength and light weight properties.
