Abstract

In this paper first a vibration model of nanocomposites is obtained, then that nanocomposites structural damping characteristics are investigated, with focus on analyzing the interfacial interaction between the carbon nanotubes (CNTs) and the polymer resin. The concept of interfacial "stick-slip" frictional motion between the nanotubes and the resin is considered. The nanocomposites damping ratio is calculated by evaluating the dissipation energy of nanocomposite. Also, the influence of different parameters such as volume fraction and length on the natural frequencies and damping characteristics of nanocomposite is investigated. Results show that of increasing volume fractions the natural frequency increases. Finally a relation between damping ratio and natural frequencies is obtained and it is found that second natural frequency increase due to increasing damping ratios.
