Abstract
It is well known that wood species and particle size used influence the bending strength of three-layer particleboard. The objective of this study was to investigate the influence of using bagasse particles in surface layer on bending strength of three-layer particleboard panels. The ratio of the mixture of bagasse and wood particles was 3:7 and 4:6 in the surface and middle layers, respectively. Press temperatures were chosen at two levels of 165 and 180 °C. Three levels of urea formaldehyde resin were selected for the surface layers, namely: 8, 10, and 12 percent. Bending strength of the panels was determined according to the procedure of European Union (EN) Standard. The results show that bagasse has a positive effect on the bending strength of boards. In this research, the treatment with 40% bagasse and 12% resin in the surface layers and a 180 °C press temperature has resulted in an optimum bagasse board product.
