Abstract

The depletion of forest resources has required the industry to seek alternative raw materials. In this context, bamboo and oil palm trunk (OPT) have gained attention as they are extensively available in Malaysia, offering potential alternatives to address the scarcity of traditional raw materials. Therefore, this study investigated the effect of pressing pressure on the physical and mechanical properties of hybrid laminated panels. The physical properties studied include density, moisture content (MC), water absorption (WA) and thickness swelling (TS) while mechanical properties evaluated include modulus of elasticity (MOE), modulus of rupture (MOR), compressive strength and shear strength. In this study, four variations of laminated panels were produced based on the configuration of bamboo Semantan (Schizostachyum grande) crush mat along with inner and outer OPT veneers labeled as SLOSL and SLISL. Bamboo was employed as the face and bottom layer, while OPT veneer served as the core layer, subjected to pressure of 22-ton force and 28- ton force. The 3-ply laminated panels were arranged in perpendicular directions the cold pressed (5kg/cm2;15 minutes) and hot pressed (25kg/cm3;15 minutes;120°C) for the 28-ton force and (25kg/cm3;20 minutes;120°C) for the 22-ton force. The adhesive, urea-formaldehyde (UF) and the hardener, Ammonium chloride (NH4Cl) were used with a spread rate of 300 g/m2. The ANOVA showed that only density and thickness swelling displayed a significant interaction between pressing pressure and material. However, among four panels, SLOSL subjected to 22-ton force showed the highest performance including density, MC, MOE, MOR and compressive strength. This study concluded that pressing pressure did not show a significant effect on mechanical properties. Hence, the hybrid laminated panel made of crushed bamboo mat and OPT veneer has a good potential to become a suitable alternative raw material for wood-based products.
