| Summary: | This research conducted to develop and study an eco friendly board that been made from a combination of oil palm empty fruit bunch (OPEFB) with artocarpus odorattisimus (mahang) mechanical behaviour especially in terms of its tensile and flexural properties. The intention of developing the eco board is to find alternative replacement materials for woods usage in modern industry as the worldwide community became concerned of major deforestation that led into global warming. The fabrication process are done by using hand lay method where the mixture of shredded OPEFB strands and artocarpus odorattisimus chip (with 4 different mixture ratio) being blended together with urea formaldehyde (UF) as binder/resin and hot pressed in a 200 ˚C mould under 300KN load to form a 150mm x 150mm x 5mm eco board. The tensile testing procedure are done to the specimen in accordance to ASTM D3039/3039m-17 test standard and a fractography of the materials are taken by using scanning electron microscope (SEM) under various level magnification to further understand root causes of materials failure. A flexural test was conducted by using “3 point bend” test method in order to acquire the flexural strength for each specimen in accordance to ASTM D1037-99 standard. From the experiment and analysis, the mixture of oil palm empty fruit bunch and artocarpus oddorattisimus in which posses best tensile properties was found and the failure pattern of the board are discussed. The addition of artocarpus oddorattisimus (ARTO) seen giving improvement on the tensile properties of the eco board (specimen D with 9.15 N/mm2), while flexural strength and also Young modulus does improve on certain amount of artocarpus oddorattisimus (ARTO) content within the mixture (33.3% of ARTO dry weight ratio). |
