The effect of acetylation process on dimensional stability and mechanical properties of plywood made by Oriental beech layers (Fagus orientalis Lipsky) were studied. The layers cut into sizes of 200×200×2 mm and acetylated in 120°C for 30 and 60 min. Thickness swelling (TS%), water absorption (WA%) and anti-swelling¬ efficiency (ASE%) of specimens were measured. Mechanical properties (MOE, MOR and impact resistance) were also tested. Results indicated that dimensional stability of acetylated plywood was significantly higher than untreated samples. MOE and MOR in severe acetylated specimens were lower than untreated, but no significant difference observed between values of impact resistance between untreated and acetylated plywoods.
