Abstract
The physicomechanical properties of bio-based sawdust-cow horn-coconut husk particleboards were determined in the present study. The particleboards were first produced using urea formaldehyde as a binder and thereafter characterized in terms of water absorption, thickness swelling, modulus of rupture (MOR), and modulus of elasticity (MOE). The thickness swelling and water absorption properties were determined at 24 and 48 h. The results of the thickness swelling at 24 and 48 h showed that boards exhibited average values of 0.55 to 1.25% and 1.40 to 2.57%, respectively, while the water absorption at 24 and 48 h gave a result of 0.71 to 1.42% and 1.08 to 2.74%, respectively. The boards also exhibited MOR with average values of 0.54 to 0.98 MPa and 12.97 to 32.37 MPa for MOE. The result shows that both water absorption and thickness swelling after 24 and 48 h decreases with an increase in the blends of sawdust, cow horn, and coconut husk. The physical properties (water absorption, thickness swelling) and mechanical properties (MOR and MOE) meet international standards confirming the strength of the manufactured boards.
