Sažetak
In recent materials science developments, composite materials are emerging as a sustainable alternative to conventional materials. Addressing the issue of annual disposal of three to four million tons of biological waste, particularly hair fibre in India, a reinforced polymer composite has been created by combining this waste with resins. Using a hand lay-up technique and constant load, a hybrid composite of Kevlar (K29) and Human hair fibre was formed, reinforced separately with Epoxy resin-556, Polyester, and Polyvinyl chloride ( PVC) separately. Conversion to ASTM standard samples allowed for an analysis using scanning electron microscopy (SEM), which revealed that the epoxy-reinforced hybrid composite exhibits high tensile strength, making it suitable for automotive parts manufacturing. While polyester and PVC-reinforced composites have advantages such as cost-effectiveness and corrosion resistance, they generally exhibit inferior mechanical properties compared to epoxy resin-reinforced composites. Epoxy resin composites are often preferred for applications where superior mechanical performance is required, albeit at a higher cost. This study not only promotes sustainability by repurposing biological waste but also demonstrates the versatility of composites in meeting diverse industrial requirements.
