Properties of jute stick binderless particleboard reinforced with bagasse pith

摘要

The paper entails improving the mechanical properties, and the dimensional stabilities of jute stick binderless particleboard (JBPB) reinforced with baggage pith. Different composition ratios of bagasse pith (BP) and jute stick (JS) particles, and pressing temperatures (180 and 200 degrees C) were used for board fabrication with a target density of 0.9 g/cm(3). The results revealed that the singlelayer admixture boards (50JS-50BP) showed higher mechanical properties and dimensional stability compared to only JS board (100JS-OBP) or only BP board (OJS100BP) at a pressing temperature of 180 degrees C. The use of BP particles at different composition ratios with JS particles for JBPBs fabrication showed better strength and stability properties than the admixture board. The properties were considerably improved by increasing the core materials of JS particles for JBPBs reinforced with BP pressed at 200 degrees C. The 20BP-60JS-20BP board with surface: core materials (40: 60) had the highest modulus of rupture (MOR), modulus of elasticity (MOE), and thickness swelling (TS) values were 25.29 N/mm(2), 3941.8 N/mm(2), and 16.56%, respectively, which satisfied the minimum requirement for type-18 of particleboard JIS A 5908 (2003). The higher proportion of small-size JS particles in the core layer and long BP particles on surface layers at 200 degrees C enhanced the bonding properties for 20BP:60JS:20BP board. Hence, it could be concluded that by controlling the composition ratio of BP and JS particles at effective pressing temperatures, high-performance binderless particleboard reinforced with BP could be fabricated.
