This work focused on the development of hybrid composites by impregnating polypropylene (PP) with vegetable sponge fiber (Luffa cylindrica) and palm kernel shell ash. The sponge fiber was chopped to 10 mm and some were treated with alkali solutions to reduce its water affinity and enhance its surface roughness. Palm kernel shell ash of
425 µm particle sizes was used to form the hybrid. Varying weight percentage of both reinforcements were dispersed randomly in polypropylene and the mixture was heated in a compression moulding machine. Thereafter, the composites mechanical and physical properties were tested. The results revealed that hybrid fiber reinforced polymer
composites has excellent flexural and tensile strengths as well as water resistance properties. Hence, the developed composites can be considered suitable for ceiling application.
