摘要

The objective of this investigation work is to enhance the mechanical properties of epoxy hybrid nanocomposites with the hybridization MWCNTs and Alumina. In this investigation, the epoxy nanocomposites properties are explored using multiwall carbon nanotubes – alumina (MWCNTs – Al2O3) filler that grown via chemical vapour deposition (CVD) and physically mixed MWCNTs – Al2O3 fillers. The mechanical characteristics of both nanocomposites are investigated with various weight fractions of 2.0, 4.0 and 6.0 wt% hybrid filler loading. The CVD grown hybrid filler epoxy nanocomposites exhibits higher mechanical properties than the physically mixed hybrid filler. The results indicated that the strong interface adhesion is achieved with homogeneous dispersion of MWCNTs – Al2O3 hybrid filler particles that observed under a field emission scanning electron microscope. It also revealed that the MWCNTs – Al2O3hybrid epoxy nanocomposites increases the tensile strength and modulus up to 66% and 38% respectively. Furthermore, the highest toughness value of 202.21 J m-3 104is achieved in epoxy-HYNC where as 166.12 J m-3 104 achieved in epoxy-PMIX with 4 wt% filler loading.
