The final objective of this study was to investigate the effect of various contents of muti-walled carbon nanotubes (MWCNTs) on the strength of a novel hybrid thermoset material. Besides, the influence of the hybrid matrix stiffness (epoxy/polyester blend) on the reinforcement role of MWCNTs were also studied. Specifically, this paper studied and evaluated the effects of weight percentages of MWCNT on the tensile strength of fabricated specimens. In addition, the morphology of the fracture surfaces of the resulting nanocomposites was examined by a field emission scanning electron microscope (FESEM). Experimental results indicated that the tensile strength of the novel nanocomposite material increases to 86.3 % with the addition of a 1% ratio of MWCNTs. Furthermore, FESEM analysis revealed that excellent adhesion and interfacing between the matrices and the fillers are the main reasons for optimum improvement of properties. The unique contribution of this study is the discovery that novel hybrid thermoset material reinforced with nano-filler (MWCNT) can be applied in making low cost, high strength and light weight components as automobile parts, transportation systems and biomedical devices.
