Keywords:
Nano Composites, Ultrasonication, Strengthening Mechanism, Viscoelatic PropertiesAbstract
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 0C 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.
