Zusammenfassung, Abstract
Wood polypropylene composites (WPC) of different compositions (30, 40, and 50%) have been prepared using maleic anhydride-polypropylene copolymer of different percentage (5 and 10% relative to their wood fiber content). Tensile, flexural, fracture toughness, and impact test of the prepared WPC were carried out. From the results, it is observed that the hard wood fiber-polypropylene composites, by using maleated polypropylene (MAH-PP), show comparatively better performance to soft wood fiber-polypropylene composites. Tensile strength and charpy impact strength have been increased to a maximum of 50 and 20%, respectively. The damping index has been decreased by 60% when 10% of MAH-PP has been used. Water absorption and scanning electron microscopy of the composites are also investigated.
