Abstract

This paper investigates the vibration and damping characteristics of hybrid nanocomposite laminates reinforced with nono-particles. A uniform laminated beam made of E-glass/epoxy enriched with Cloisite 30B is considered for vibration analysis. Effects of the volume fraction of nano-particles on vibration response and damping coefficients of the beam have been studied using a layerwise displacement theory. Experimental illustration has been set up to compute the free vibration response and damping coefficients of the nano-composite laminated beam. Increasing the volume fraction of nano-particles from 1 to 5% increases the natural frequency of the sample fixed-free beam from10.88 to 11.66 Hz and its damping coefficients from 0.041 to 0.055.
