Abstract
Polymer nanocomposites (PNCs) have recently grown in material research because of their dominant applications and strength compared to their counterparts. In this study, Silicon Dioxide (SiO2 )-Epoxy Nanocomposite (SENC) with 1 %, 2 %, and 3% nano-silica fillers by weight reinforced in epoxy and 0.5 % weight of Graphene in Epoxy Nanocomposite (GENC) is made with solution casting method. The specimens were tested for flexural strength. The comparative plots of stress-strain and force-extension are drawn for neat epoxy along with 1 %, 2 %, 3% SENC, and 0.5 % GENC. It is observed that 3% SENC shows better flexural strength than neat epoxy, 1% SENC, 2 % SENC, and 0.5 % GENC. Also, GENC shows better toughness and stability even at a low fractional concentration of 0.5% compared to neat epoxy, 1%, and 2% SENC. However, 0.5% GENC has lower flexural strength than 3% SENC.
