✦ Synopsis

Abstract

A micromechanics model is developed to calculate the effective elastic modulus of composite with aligned straight carbon nanotubes (CNTs). The interfacial bonding between CNTs and polymer matrix gives an important effect on reinforcing specification of CNTs. The nonlinear cohesive law is used to describe the interface debonding. The effect of debonding at CNTs/polymer interface and the van der Waal's (vdw) force between carbon atoms is studied on the mechanical properties of composite reinforced by CNTs. It is also shown that small CNTs have stronger reinforcing effect than larger ones. The debonded nanotubes behave like voids in the matrix and it can significantly reduce the stiffening effect of the nanocomposites. POLYM. COMPOS., 2011. © 2011 Society of Plastics Engineers
