Biocomposites offer a significant non-food market for crop-derived fibers and resins. Considerable growth has been seen in the use of Biocomposites in the automotive and decking markets over the past decade. Over the last decades, research has increasingly been conducted on renewable materials from Sustainable resources for a variety of applications. There are lots of waste materials available during fabrication process like Polyethylene, Polypropylene, polystyrene etc. These wastes constitute nuisance to the environment not only in India but the world at large. The ability to convert these wastes into useful engineering materials e.g. composites sharpens the focus of this present research work. From the available literature no investigation has been conducted on the application of the leaf sheath of betel-nut plant (Areca Catechu) in polymer composite materials. Fiber modification includes mercerization and Silanation for enhancing better surface interaction towards polymer matrix. Based on the above-mentioned situation, the study described in this work intends to study the mechanical properties of recycled PP composites reinforced with Leaf Sheath Areca Fiber.
