Heat treatment is often applied to wood species to improve their dimensional stability. This study examined the effects of heat treatment on certain mechanical properties of laminated beech wood (Fagus orientalis L), which has industrially high usage potential and large plantations in Turkey. Wood specimens obtained from Simav- Kutahya, Turkey. For this purpose; first beech wood samples used in this study were kept in temperatures of 100 degrees C and 150 degrees C for 4 hours, and after that they were laminated with polyurethane and polyvinyl acetate adhesives. The test results of heat-treated laminated beech wood and control samples showed that mechanical properties including compression strength, bending strength and bonding strength effected positively with heat treatment, and increase in temperature and duration further increased strength values of the laminated wood specimens.
