Effect of different configurations on the properties of hybrid laminated bamboo-oil palm trunk composites

Advancements in hybrid laminated composite production have increased the value of bamboo and oil palm trunk (OPT) materials, enabling the development of renewable resource-based composites. This study evaluates the effect of bamboo-OPT configuration on the properties of hybrid laminated bamboo-OPT composites. Two Malaysian commercial bamboo species, namely semeliang (Schizostachyum grande) and semantan (Gigantochloa scortechinii), along with OPT veneer, were used. Various configurations of three-layer laminated mono-species bamboo, OPT, and hybrid bamboo-OPT composites specifically semeliang-OPT (SM-O) and semantan-OPT (SN-O) with dimensions of 9 mm (thickness) × 300 mm (width) × 300 mm (length) were fabricated using an impregnation modification method with low molecular weight phenol formaldehyde resin (LMwPF). The physical, bonding shear, and mechanical properties of the composites were evaluated. Results showed that the hybrid SM-O composite had the lowest thickness swelling of 1.55% and water absorption of 10.01% after 24 h immersion, indicating superior dimensional stability. In terms of bonding performance, SM-O achieved shear strengths of 2.94 N/mm2 after 24 h soaking and 2.11 N/mm2 after boil-dry-boil treatment, meeting the minimum standard requirement. For mechanical performance, SM-O displayed the highest modulus of rupture (MOR) at 189.08 N/mm2 and modulus of elasticity (MOE) at 28,627 N/mm2, outperforming both mono-species bamboo and OPT composites.
