The objective of the study was to determine and compare the effects of the different heat treatment media on the physical and mechanical properties of Paulownia tomentosa and Pinus koraiensis woods. Heat treatment was conducted in oil and air at 180, 200, and 220°C for 1, 2, and 3 hours. The properties of the heat-treated woods including color, weight, density, volume shrinkage, compression strength, and hardness, were investigated. Oil heat-treated wood exhibited a darker color than the air heat-treated wood. Weight and density of oil heat-treated wood showed a remarkable increase, but those of air heat-treated wood slightly decreased. Oil heat-treated wood exhibited lower volume shrinkage compared to air heat-treated wood. Axial compressive strength increased by oil heat treatment at all temperatures, while in air heat treatment the axial compressive strength increased at 180 and 200°C and decreased at 220°C. The hardness of oil heat-treated Pinus koraiensis wood increased, in contrast with Paulownia tomentosa wood. In air heat treatment, both wood species showed a decrease in hardness. In conclusion, there were some differences in the effect of the heat treatment media on the physical and mechanical properties between the two wood species and heat treatment in oil is more effective method to improve some wood properties than heat treatment in air.
