ABSTRACT = {The mechanical properties of hybrid nanocomposites made of epoxy/glass fibre dispersed
with nano-α-Al<sub>2</sub>
O<sub>3</sub>
 powder at different weight percentages were studied.The effect of nano-α-
Al<sub>2</sub>O<sub>3</sub>
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-Al<sub>2</sub>
O<sub>3</sub>. The properties
varied with the loading and size of the nanoparticles. The tensile strength was highest for
0.5 wt% of 200nm nano-α-Al<sub>2</sub>O<sub>3</sub>, which is 167.80 N/m<sub>2</sub>.The highest flexural strength was
observed for 1.5 wt% of 60nm nano-α-Al<sub>2</sub>
O<sub>3</sub> based laminates which was 378.39 N/m<sub>2</sub>
 and
the highest interlaminar shear strength (ILSS) was observed for 0.5 wt% of 60nm nano-α-
Al<sub>2</sub>O<sub>3</sub> , which is 31.21 MPa and the highest Vickers hardness was found to be 86.72 for 1.5
wt% of 60nm nano-α-Al<sub>2</sub>
O<sub>3</sub>.},
