In the present work the dynamic response of laminated composite beam reinforced with nano-particles has been investigated. Most of the existing works on the effects of nano-particles on stiffness of the composite structures are limited to very low weight fraction, around 3% to 5%. This work studies the effect of higher percent of Nano particles (up to 10%) on the dynamic behavior of the composite structures via experimental tests. Adding Nano clay up to 3% of weight fraction increases the natural frequency, beyond that up to 5 % the natural frequency slightly decreases and at 10% a sharp reduction in natural frequency is observed. Another feature of importance is the increasing damping coefficient of laminated beam when the amount of nano-particles reaches to 10%.
