Damping Augmentation of Nanocomposites Using Carbon Nanotube/Epoxy

Abstract

In a nanotube-based polymeric composite structure, it is anticipated that high damping can be achieved by taking advantage of the interfacial friction between the nanotubes and the polymer. The purpose of this paper is to investigate the structural damping characteristics of polymeric composites containing carbon nanotubes with various kinds and amounts. The damping characteristics of the specimens with 0, 0.5 wt% nanotube contents were computed experimentally. Through comparing with neat resin specimens, the study shows that one can enhance damping by adding CNT fillers into polymeric resins. Similarly experiment showed that the maximum value of damping ratio was obtained at 0.5 wt%.
