Abstract
Utilisation of sawdust-like hybrid composite is one innovative way to reduce the usage of wood-based material and at same time reduce the abundance of wood waste. Effects of different resin content and densities on the properties of hybrid wood sawdust-Acacia mangiumcomposites were investigated in this study. Three-layered hybrid composites from sawdust and Acacia mangiumwere fabricated with different resin content and densities within the face/back (sawdust) and core (Acacia mangiumparticles). Two different resin contents, 8:10:8 and 12:10:12, were used with 500, 600 and 700 kg/m3 board densities. Urea formaldehyde (UF) was used as a binder with addition of wax. The properties of bending strength (MOR and MOE), internal bonding strength (IB), thickness swelling (TS) and water absorption (WA) were evaluated based on Japanese Industrial Standard, JIS A 5908:2003 Particleboard (2003). The results showed that there were significant interactions between resin content and densities on hybrid wood sawdust-Acacia mangiumcomposites. The result obtained indicated that bending and internal bonding strengths of the panel bonded using 12:10:12 resin content with 700 kg/m3 density were better compared to 8:10:8 resin content. Thickness swelling and water absorption rate were reduced for the panel bonded with 12:10:12 resin content compared to 8:10:8 resin content. When the density increased, the physical properties and thickness swelling were decreased. It is expected that hybrid composite from sawdust can be commercialised into a value-added product in wood-based industry.
