Description
Summary:In this paper, the bending analysis of Multi-wall carbon nanotubes (MWCNT) reinforced honeycomb core sandwich composite plate has been performed based on the higher-order shear deformation theory using finite element formulations. The parametric study on the static behavior of honeycomb sandwich composite plates hybrid with MWCNT with the influence of the weight percentage of CNTs for core material and upper and bottom skins with various boundary conditions, different ply configuration was performed. The numerical study clearly shows that the bending deflection decrease with an increase in the weight percentage of MWCNTs. The boundary condition C-C-C-C has the lowest deflection while the C-F-F-F end condition has the highest deflection irrespective of ply configuration considered. The deflection of the sandwich plate with MWCNT can be found almost two times lower than deflection without MWCNT due to higher stiffness offered by fillers. It can be observed that the influence of MWCNT in the core is least contributing to increasing the stiffness with the influence of MWCNT in the skins on the bending characteristics. Finally, It can be concluded that this study reveals the influence of adding fillers in the core and skins has much difference in the bending characteristics of MWCNT reinforced honeycomb core sandwich composite plate.
