Abstract: The aim of the work was to fabricate and characterise a novel nanocomposite material that is a multiphase hybrid polymer composite with MWCNT filler. The optimisation of process parameters on tensile strength of epoxy/polyester/MWCNT nanocomposites using the Taguchi method was performed. The contribution of each process parameter on the output response was then analysed using analysis of variance (ANOVA). Experimental specimens were then made to confirm optimum values for each process parameter. The results indicated that the tensile strength of the optimal nanocomposites was improved to 86.3% with the addition of MWCNTs at a ratio of 1%. The results of nanoindentation tests exhibited the enhancement of Young's modulus and hardness by 71% and 27.5%, respectively, at 1% of MWCNTs. Morphologies of the fracture surface of resulting nanocomposites observed by a field emission scanning electron microscope (FESEM) showed good adhesion between the fillers and the resin.
