Comparative Analysis of Flexural Strength of Silicon Dioxide Epoxy Nanocomposite and Graphene Epoxy Nanocomposite

Kriti Sahai and Audhesh Narayan

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.
