  Abstract

In this study, the elastic properties of the various honeycomb core configurations tailored with MWCNT filled glass fiber reinforced polymer composite materials (GFRP) were investigated numerically using vibration based techniques and verified with experimental works. The shear properties of GFRP and CNT-GFRP strips corrugated hybrid honeycomb core structures with the influence of Armchair and Zigzag arrangement in CNTs using the vibration analysis have been carried out along the out of plane with respect to Gxz and Gyz directions. The fabrication of honeycomb core using MWCNT filled glass fiber reinforced polymer composite materials (GFRP) were prepared with corrugation method after preparing the lamina using vacuum bagging assisted hand layup technique and tested using vibration based techniques for verifying the developed numerical formulation. Finally, the parametric study was carried out to identify the effects of the addition of various different types of CNT; weight percentages of MWCNT, different ply orientations of the fibers, various honeycomb configurations and honeycomb cell size. It was observed that significant difference is noticed in the shear characteristics of the honeycomb with respect to the variations in the parameters considered. Further, it was noticed from the analysis that the honeycomb structures made by the insertion of strips in various locations of the hexagonal honeycomb cells could yield higher shear moduli than that of the conventional honeycomb structure. It can be concluded that the vibration based techniques implemented for evaluation the elastic properties of the various honeycomb core configurations tailored with MWCNT filled GFRP composite materials and results extracted could support the designers for developing various cell core with the addition of MWCNT for the light weight applications such robots, aircraft and automobile applications.
