The mechanical and thermal characteristics composites reinforced with E-glass fibre were examined in the current study. The mechanical stirring technique followed by the hand layup method was used to make composites loaded with different weight percentages of nanographene and a layer of e-glass. Nano-composite is made up of three different compositions by adjusting the weight percentages of each nanomaterial by 1%, 2%, and 3%. The generated nanocomposites' mechanical characteristics, including flexural strength, tensile strength, TGA, DTA, DSC, and hardness, were investigated and compared on a varying of nanofillers. The results showed that, when compared to neatly stacked composites, the introduction of nanographene (NG) composites can be a successful strategy in terms of mechanical qualities. Results are presented after examination of the experimental values of 1, 2, and 3 wt% of nanographene in the E-glass fabric reinforced composite. Additionally, it was found that adding nanomaterials the mechanical and thermal properties of nanographene to decrease after reaching their optimum weight percentage.
