In the present work, In-situ polymerization technique synthesized epoxy alumina polymer nanocomposite. Dispersion of alumina nanoparticle of rod shaped and spherical shape with size 20nm-50nm, were achieved by ultra-sonication processing technique. Effect on mechanical properties (Tensile and viscoelastic properties) because of the post curing temperature on nanocomposites were determined. Postcuring temperatures 60, 80, 100, 120 and 1500°C were selected. Tensile strength with young’s modulus, and storage modulus of neat epoxy specimen as well as nanocomposite with different wt.% of nanoparticle showed decrement with increase in temperature, while glass transition temperature increased. Mechanical properties were maximum for nanocomposite with 0.1 wt. % nanoparticle for all Postcuring temperature. It was observed that Nanocomposite with rod shape showed good mechanical properties.
