Abstract

The mechanical properties of hybrid nanocomposites made of epoxy/glass fibre dispersed with nano-α-Al2 O3 powder at different weight percentages were studied.The effect of nano-α- Al2O3 size and wt% on mechanical properties like tensile, flexural, interlaminar shear stress and hardness enhanced because of their higher surface area and interfacial polymer-metal interaction. The nanoparticle embedded laminates have shown improvement in flexural strength,and hardness when compared to laminate without nano-α-Al2 O3. The properties varied with the loading and size of the nanoparticles. The tensile strength was highest for 0.5 wt% of 200nm nano-α-Al2O3, which is 167.80 N/m2.The highest flexural strength was observed for 1.5 wt% of 60nm nano-α-Al2 O3 based laminates which was 378.39 N/m2 and the highest interlaminar shear strength (ILSS) was observed for 0.5 wt% of 60nm nano-α- Al2O3 , which is 31.21 MPa and the highest Vickers hardness was found to be 86.72 for 1.5 wt% of 60nm nano-α-Al2 O3.
