This paper presents numerical analysis of Young’s modulus of MWCNTs/MnO2nanocomposite. The solution method has been usedto fabricate of 5, 10 and 15 wt% of MWCNTs/MnO2nanocomposite powder. The Young’s modulus of MWCNTs/MnO2nanocomposites was determined using analytical models include Voigt and Reuss bounds, Hashin and Shtrikman bounds, Halpin–Tsai model, Hui-Shia model. Voigt upper bound, Halpin-Tsai and Hui-Shia models predict nearly same Young’s modulus of MWCNTs/MnO2 nanocomposite in longitudinal direction. The various models also indicate that incorporating MWCNTSs in MnO2 matrix can potentially improve mechanical properties composites significantly.Halpin and Tsai proposed the equations for discontinuous short CNTs, randomly oriented in a matrix; the effective Young’s modulus of the nanocomposite also increases with wt% of MWCNTs.
