The present work aims to fabricate and characterize epoxy based composites with varying wt. % of nanoparticles as filler and to investigate and analyze the effects of nanoclay and nanocarbon with different wt. % on the epoxy resin. Different types of composites are prepared using 0, 2, 4 and 6 wt. % of fillers with rest of epoxy resin. Fillers are mixed with the resin by high speed mechanical stirrer for 2 hours. The mixture is transferred to the mould and allowed to cure. The specimens are prepared based on ASTM standard. The specimens are tested for tensile and flexural strength. Adding fillers resulted in change in the basic properties. ANOVA is applied to find the significance effect of 4 different weight percentage of fillers and different variety of fillers on the properties of composites.
