Abstract
This study aimed to determine and compare the effects of heat treatment in palm oil and air on the physical and mechanical properties of Paulownia tomentosa and Pinus koraiensis wood. The heat treatment was conducted at 180, 200, and 220 °C for 1, 2, and 3 h. The characteristics of the wood before and after heat treatment, such as density, volume shrinkage, abrasion, axial compressive strength, and hardness, were investigated. Heat treatment in oil caused a significant increase in wood density, whereas the density of air heat-treated wood decreased. Oil heat-treated wood exhibited lower volume shrinkage and weight loss in abrasion compared to air-heat-treated wood. The axial compressive strength of both wood samples heat-treated in oil and air was the highest at 180 °C, and then gradually decreased as the temperature and treatment duration increased. Oil heat treatment increased the hardness of Pinus koraiensis wood, in contrast to Paulownia tomentosa wood. The hardness of both wood samples decreased with air heat treatment. In conclusion, it was revealed that there were some differences in the effect of physical and mechanical properties by heat treatment methods between wood species. Oil heat treatment was a more effective method for improving the properties of both woods compared to air heat treatment. Seung Hwan Lee, Fauzi Febrianto & Nam Hun Kim
