Coir fiber was selected for this study as it is non-toxic, low cost, high lignin content, low density, low cost, high lignin content, low density, low tensile strength, low tensile modulus and high range of elongation compared to other fibers. Composites were prepared using Coir fiber in the rough (raw) stage, after washing with tap water, and also subjected to various other treatments. After which their mechanical composition, Tensile, compressive, Flexural properties were determined and the results are discussed in the laboratory. There was a good improvement in their properties due to Mechanical composition modification and surface modification (fiber / matrix adhesion).
