Abstract

This study presents the manufacturing of medium density fiberboard (MDF) produced from a mixture of Leucaena and rubberwood species. The evaluations are conducted to determine the physical and mechanical properties of MDF from the mixture of Leucaena and rubberwood and the effect of different wood ratios and resin content on fiberboard properties. The usage of urea formaldehyde (UF) as a particleboard binder and target board density of 700 kg/m3 were studied. Medium density fiberboards were assessed for the properties of mechanical (bending and internal bonding) and physical (thickness swelling) according to European Standard (EN 622-5:2006). Results shows that fiberboard made from 80% Rubberwood and 20% Leucaena and 12% resin content has the highest Modulus of Rupture (MOR) value of 15.09 MPa. Whereas, fiberboard made from 20% Rubberwood and 80% Leucaena and 12% resin content has the highest Modulus of Elasticity (MOE) and Internal Bond (IB) values of 2005 Mpa and 0.7 Mpa, respectively. Fiberboard made from 80% Rubberwood and 20% Leucaena and 12% resin content has the best Thickness Swelling (TS) value of 21.59%. The results revealed that the variations in wood ratios and resin contents shows significant effect on MOR, MOE and TS values of fiberboard. However, there is no significant changes on IB values with the usage of different Leucaena and rubberwood ratios.
