The effects of heat treatment on the some properties of beech and oak wood

Wood has been used to many advantages such as their easy processing, strength values, and price in the many sectors. For all that, wood materials have many disadvantages such as high hidrofilic behavior, low thermal stability. The various treatment technics were used to overcome the disadvantages. The heat treatment of wood materials is one of the technics. The aim of this study was to determine the physical, thermal and mechanical properties of heat-treated wood at 180°C and 220°C for 8 h. After heat treatment process; mechanical properties such as flexural MOR and MOE, compression MOR and lap shear strength, physical properties such as density and water intake, thermal properties such as thermal stability with TGA were investigated. According to the obtained results, physical and mechanical properties of heat-treated wood materials decreased, and while temperature in the heat treatment was rising from 180°C to 220°C, physical and mechanical properties decreased more. Thermal stability was determined to increase with thermogravimetric analysis.
