Abstract:
World is now focused on alternative, environmentally friendly and biodegradable material sources.
Because of the growing natural concerns, bio composite produced from regular fiber and
polymeric resin is one of the company's late advances and constitutes the current scope of
experimental work. The use of composite materials is gradually increasing. The composite consists
predominantly of two phases, matrix and fiber. Accessibility of characteristic fiber and ease of
assembly have led scientists around the world to try and learn about the viability of protection
resolves and the degree to which they fulfill the necessary specifications of broad enhanced
polymer composite by regional standards.
Natural fiber-based composites are under intensive study due to their environmentally friendly
nature and unique properties. The advantage of natural fibers is their continuous supply, easy and
safe handling and biodegradable nature. While natural fibers exhibit admirable physical and
mechanical properties, they vary with the source of plants, species, and geography. Pineapple and
palm leave fiber is one of Ethiopia's abundant materials and has not yet been studied as necessary.
A detailed study of mechanical properties will bring out logical and reasonable utilization of palm
and pineapple leaf fiber composite for various applications. In this research, covered the tensile,
compressive, and bending stress ,young’s modulus, elongation of palm and pineapple leaf fiber
composite and compared with the corresponding properties with E and S glass fibers. Stress of
material is (356-2097KPa) & (70-790KPa) for palm and pineapple leaf fiber epoxy composite
respectively. Fiber extracted from Palm leaf have more strength as compared to pineapple leaf
fiber. Tensile modulus of the material is (51-414KPa) & (4.81-459KPa) for palm and pineapple
leaf fiber epoxy composite respectively. Young’s modulus of pineapple leaf fiber is some more
bigger as compared to palm leaf fiber due to it pineapple leaf fiber have large strain. Strain of the
material developed is (5.07-6.97%) & (11.01-14.52%) for palm and pineapple leaf fiber epoxy
composite respectively. Bending strength of the material is 13MPa and 24MPa for palm and
pineapple leaf fiber epoxy composite respectively.
