In this paper, the effects of adding carbon nanotubes to quasi-static punch shear properties (QS-PS) and mechanical properties of hybrid laminated composites has been investigated experimentally. The nanocomposites have 12 layers of 2D woven glass fiber with area density of 200g/m2, is manufactured by Hand lay-up method. Epoxy resin systems is made of a diglycidyl ether of bisphenol A (DGEBA), Epon 828, as the epoxy prepolymer and Epikure F-205 as the curing agent. In this study, was used the multi-walled carbon nanotube (MWCNTs) modified with hydroxide (-COOH), with weight fraction 0, 0.1, 0.5 and 1 respect to total weight of resin. Results of tensile test have showed, addition of carbon nanotubes can change tensile properties of matrix. Maximum increase can be seen in modulus of the resin of 0.5% nanotubes content around 31%. Moreover, the results of tensile properties of hybrid laminated nanocomposites show maximum change in toughness of sample of 0.5% nanotube content around 14% with increasing tensile strength and fracture strain. The results punch shear test show that the adding of carbon nanotubes has little effect on total energy absorbed so that maximum increase is around 4% in sample of 0.5 %.
