Investigation of Mechanical and Chemical Properties of the Coir Fiber and Wood Powder Reinforced Hybrid Polymer Composite

In many engineering applications, natural fibers are used because of high strength, low weight, and easy availability. In many composite studies reveals among the various natural fibers, the coir fiber is used as a reinforcing agent in polymer composites. In this paper, the mechanical and chemical properties of the hybrid polymer composites reinforced with coconut coir fiber and wood powder at different fractions were studied. The hand layup technique is used for sample preparation as per ASTM D638-03 standards. The mechanical and chemical properties such as tensile strength, flexural strength, and impact strength and water absorption capacity of the hybrid polymer composite were tested for different specimens prepared as per ASTM D638-03 standards. The results of the above tests prove that the coir fiber and wood powder have a significant influence on the mechanical properties of the hybrid polymer composite.
