Polymer composites are widely used in various industries such as aerospace, automotive, and defense due to their high specific modulus and specific strength properties. These materials offer advantages such as reduced fuel consumption owing to their low density and can be easily processed into complex geometries using conventional manufacturing methods (Du & Cheng, 2012; Hsissou et al., 2021). Graphene oxide (GO) plays a crucial role as a filler material in nanocomposites due to its high surface-to-volume ratio, excellent dispersibility in both aqueous and organic solvents, and extensive reactive surface functional groups, which facilitate strong interactions with polymer matrices. These properties prevent aggregation, improve processability, and strengthen interactions between fillers and polymers (Compton & Nguyen, 2010). Furthermore, the superior mechanical properties of GO, such as its high Young's modulus and tensile strength, contribute to the enhancement of mechanical performance in polymer composites (Abdullah & Ansari, 2015). GO contains oxygen functional groups such as hydroxyl, epoxy, and carboxyl, which readily interact with polymer matrices (Phir, et al., 2017). These functional groups enhance the compatibility of GO and reduced graphene oxide (rGO) with polymer matrices, broadening their application in nanocomposite production. rGO has a structure similar to GO and can be produced via chemical or thermal reduction processes. Despite the reduction process, some functional groups remain on the surface (Phir,et al., 2018). When used as a reinforcement in polymer matrices, rGO improves mechanical properties such as Young's modulus, tensile strength, and toughness compared to pure polymers (Jang et al., 2014). This study aims to investigate the mechanical and thermal properties of polypropylene (PP) composites containing different concentrations of rGO.
