This study aims to evaluate how SiO2 fiber additions affect the mechanical properties of hybrid nanocomposites composed of polypropylene (PP), sisal, and Kevlar fibers. Different concentrations of SiO2 are integrated into these composites to systematically analyze their tensile, flexural, and impact strengths. Utilizing G-power calculations with 80% power and α = 0.05 ensures robust statistical analysis, which indicates significant variations in mechanical properties across SiO2 compositions (p < 0.05). The results reveal that higher SiO2 fiber content significantly enhances the mechanical performance of the composites, suggesting potential applications in advanced materials engineering. This study underscores the importance of SiO2 in improving the mechanical properties of PP/sisal/Kevlar fiber hybrid nanocomposites.
