Abstract – The objective of this research was to evaluate the effect of wood species and layer structure on the physical and mechanical properties of OSB made from Maesopsis eminii , Paraserianthes falcataria, and Acacia mangium collected from planted forest. OSB bonded with methylene diisocyanate resin were produced with three types of layer structure namely perpendicular, parallel, and random orientation. The results indicated that OSB manufactured from wood with lower density (P. Falcataria) had higher mechanical properties (MOR, MOE and IB) and lower dimensional stability (water absorption and thickness swelling) compared to OSB manufactured from higher density (A. mangium). Strand orientation strongly affected the physical and mechanical properties of OSB with perpendicular orientation showed superior performance as compared to parallel and random orientation. Physical and mechanical properties of OSB made from fast growing tree species met the requirement of CSA 0437.0 standard for grade O-1 OSB panels. The results showed the feasibility of using wood strands of fast growing tree species from planted forests for OSB manufacturing, which is important to qualify appropriate raw material supply for the board industry.
Key words: OSB, fast growing species, layer structure.
