Natural fiber has received wide attention from researchers all over the world because of their advantages, which are environmentally friendly and cost-effectiveness. There are different plant fiber among various plant fiber, water hyacinth one source of natural fiber and the plant resource used for animal feed, organic fertilizer, for making paper, bag, basket, and tablecloth. So far, the water hyacinth plant has not been used as a reinforcing material for composites. The goal of this research work is to fabricate water hyacinth fiber reinforced polyester composites with a view to characterized the mechanical properties of water hyacinth fiber reinforced polyester composite material. The fiber extract manually after collecting the water hyacinth plant from Lake Koka in the Oromia Region, Ethiopia. Once the extraction done, the fiber treated by a chemical in different sodium hydroxide concentration, used for the improvement of bond & interfacial strength of the water hyacinth fiber and the fiber density performed using Pycnometer method by ASTM standard. Fabricate the water hyacinth fiber reinforced polyester composite using hand lay-up methods in different fiber/matrix ratio and mechanical properties also specimen measured according to ASTM standard and the prepared composite material experimentally analyzed. The result showed that water hyacinth fiber have a lower density comparing with common natural fiber and all the mechanical properties satisfactorily improved for chemically treated water hyacinth fiber polyester composites in comparison with those of raw water hyacinth fiber polyester composite. Therefore, using water hyacinth fibers as reinforcement in a polymer matrix successfully develops a composite material. |
