Abstract
This paper presents an analytical model to describe the influence of mechanicaldeformation on the effective electrical conductivity of CNTs reinforced composites. The modelshows that the effect of mechanical strain on the effective electrical conductivity of CNTsreinforced composites are via two mechanisms; one is the strain-induced alteration of volumefraction of inclusions and the other is the strain-induced change of the tunnelling electricalconductivity of inclusions. Analytical formulations are developed for calculating thedependence of the effective electrical conductivity of the composite on the mechanical strain.The model is validated by using experimental data published in literature for CNTs reinforcedpolymer composites.
