This study was conducted to evaluate the physic-mechanical properties of three-layer particleboard made from sorghum stalk and sugarcane bagasse hybrid reinforced bonded with urea-formaldehyde resin. The production of particleboards using the sorghum and bagasse particles has been established at the ratio of (25:50:75) sorghum stalk and sugarcane bagasse with urea formaldehyde as a matrix at different concentration (50 kg/m3, 60 kg/m3 and 70 kg/m3) and pressing pressure (18 MPa, 20 MPa and 22 MPa) through hand mixing from 3 to 5 minutes and then hot press within a temperature range of 160oC to 180oC for 4 minutes. The particleboards were produced with their proportions through Taguchi design of experiment (L9) approach and the experimental results were analysis using analysis of Taguchi design and ANOVA with general linear model. The experimental results showed that, internal bonding, flexural strength, modulus of elasticity and moisture content were significantly improved with increase of the resin content and pressing pressure 18 MPa to 22 MPa. The thickness swelling value also dropped where the resin concentration varying from 50 kg/m3 to 70 kg/m3 and showing better stability of the board while the water absorption increase as resin content were increased. Results from ANOVA provides that SS3B1P3UFR3 (3:1 ratio of Sorghum with Bagasse, 22 MPa of pressing load and 70 kg/m3 urea-formaldehyde concentration) is the most optimal combination of variables for the better performance of particleboard.
