“Generating a eco friendly reinforced composite using human hair and analyzing it for commercial use”

Abstract

This paper delves into the development and characterization of natural hair fiber-reinforced polymer composites, with a focus on their physical and mechanical attributes. Composite materials encompass ceramic matrix composites (CMC), metal matrix composites (MMC), and polymer matrix composites (PMC), with PMC being favored for its cost-efficiency and ease of production, notably employing thermoplastic polymers for recyclability. Natural fibers are gaining traction, especially in the automotive industry across Asia and Europe, due to their low density and environmental friendliness. Human hair stands out as a reinforcing material owing to its impressive tensile strength, sustainability, abundance, and keratin content. The paper addresses challenges linked to natural fibers in composites, including moisture resistance and dimensional availability. The research involves creating composites using human hair fibers, epoxy resin (polypropylene), and specific molds, varying hair fiber percentages. Detailed methodology covers materials, equipment, mold prep, specimen prep, and mathematical modeling. Tensile, flexural bending, and impact strength tests reveal insights into composite mechanics. Hair fiber additions strengthen the polymer matrix, particularly at 5 to 15 weight percentages, though flexural strength diminishes compared to non-reinforced composites. Higher hair fiber percentages enhance hardness. In conclusion, this study showcases human hair fiber's potential as a reinforcement in polymer composites, emphasizing the need for further exploration of matrix-fiber adhesion to boost composite performance. These findings contribute to the growing interest in natural fiber composites for sustainable and economical applications.
