Prediction of the piezo-resistive behavior of rubber/carbon nanotube nanocomposites under quasi-static compression

This paper presents the prediction of piezo-resistive behavior under quasi-static uniaxial compression loads using Percolation Excluded Volume (PEV) approach. The PEV approach is supplemented by Finite Element (FE) simulations to calculate displacements Carbon Nano-Tubes (CNTs) embedded in a polymer matrix. number contacts between CNTs determined minimum distance threshold (tunnelling distance). FE model based on experimental parameters and CNT data. carried out LS-Dyna solver made it possible variation electrical resistance, which was found be accordance with its counterpart. resistance increases when are mostly oriented orthogonally loading direction. For other orientations, decreases.
