Comparing Kevlar Fiber influence on PP/sisal/SiO₂ nanoparticle fillers/Kevlar hybrid nanocomposites with plain nanocomposite for enhanced mechanical properties

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.
