The present study deals with the preparation of natural fiber reinforced polystyrene composites by compression molding technique in which good interfacial adhesion is generated by fiber surface modification. The fiber surface was modified through graft copolymerization of methyl methacrylate onto the fiber surface. The short grafted fibers were then spread between the alternate layers of polystyrene resin by hand lay up method to obtain the composites. The samples of the composites thus prepared were characterized by FTIR spectroscopy, scanning electron microscopy and thermogravimetric analysis. The composites were then evaluated for mechanical properties like tensile strength, compressive strength, flexural strength and wear resistance etc.
