This study presents a comparative analysis of coir and banana fiber reinforced polymer resin
composites, focusing on their mechanical and environmental performance characteristics using
the hand lay-up method. Natural fibers such as coir and banana offer sustainable alternatives
to traditional synthetic reinforcements due to their renewability, low cost, and biodegradability.
The research involves fabricating composite samples through the hand lay-up process, which
is a widely used technique in composite manufacturing for its simplicity and cost-effectiveness.
Samples with varying fiber content are prepared, ensuring consistency in resin impregnation
and fiber distribution. Comprehensive mechanical testing, including hardness, wear and micro
structural analyses, is conducted to assess the performance of each composite type. The
findings aim to provide insights into the mechanical properties and environmental
sustainability of coir and banana fiber composites compared to traditional synthetic
composites. It can be contributes to understanding their potential applications in industries such
as automotive, construction, and packaging, where lightweight, strong, and eco-friendly
materials are increasingly in demand.
