Abstract
This paper presents the results of an investigation of the structural damping characteristics of polymeric composites containing randomly oriented nanoropes. The SWNT (single-walled nanotube) rope is modeled as a closed-packed lattice consisting of seven nanotubes in hexagonal array. The composite is described as a three-phase system consisting of a resin, a resin sheath acting as a shear transfer zone, and SWNT ropes. The "stick-slip" mechanism is proposed to describe the load transfer behavior between a nanorope and a sheath and between individual SWNTs. The analytical results indicate that both the Young's modulus and loss factor of the composite are sensitive to stress magnitude. Also, to address the orientation effect on inter-tube sliding and tube/sheath sliding, the Young's moduli and loss factors of composites filled with aligned nanoropes and randomly oriented nanoropes are compared.
