In the past decades, due to population and technical development, the pollution in the world has increased. Most of the products are developed from petroleum derivatives. The petroleum-based derivatives have some problems like pollution, availability, and cost of products. So, this research is work focused on the composite materials for petroleum derivative-based materials which are used in home appliances. The primary aim of the research is developing suitable natural fiber composite for the right application. For preparing composite material, the coir fiber has been selected for good mechanical strength, availability and low cost. In this research, mechanical testing named tensile, impact, flexural and water absorption testing were examined. The specimen for the experiment was prepared in different ratios of coir and polypropylene. The coir fiber is finely chopped in 3mm length and mixed with polypropylene. The pressure and temperature are applied through compression moulding machine, it creates high pressure on the fiber. The coir fiber mixed with polypropylene with the ratio of 0% coir and 100% polypropylene, 10% coir and 90% polypropylene, 20% coir and 80%, 30% and coir 70%, 35% coir and 65% polypropylene. Finally, the best ratio is picked from the examined results
