Mechanical Properties of Thermally Modified Corymbia Citriodora and Eucalyptus Saligna Woods
ABSTRACT This study aimed at evaluating thermal modification in mechanical properties of Corymbia citriodora and Eucalyptus saligna woods compared with a control. To do so, three samples of each species were selected, with approximately 40 years, which had the first two three-meter long logs removed. Wood thermal modification was done through final temperatures of 140 °C, 160 °C e 180 °C for 2.5 hours, and the control as well, using a forced air circulation greenhouse. Mechanical properties tests consisted of maximum impact resistance evaluation, static bending, and fiber parallel compression. Generally, results showed that thermal modification increases wood resistance up to a certain point and reduces in the highest temperature.
