The Effect of Artificial Weathering on Surface Properties of Thermally Modified Oriental Beech Wood

The study aimed to determine some surface parameters such as surface roughness and color changes of thermally modified Oriental beech (Fagus orientalis L.) wood samples after 750 hours of artificial weathering. The results of the study showed that artificial weathering led to an increase in surface roughness of Oriental beech wood. Thermal modification interval of 210 degrees C - 230 degrees C gave a smoother surface than unmodified samples after artificial weathering. Artificial weathering caused darker, reddish, and yellowish tone of unmodified and thermally modified Oriental beech wood. According to the study findings, surface properties of thermally modified Oriental beech wood were better than those of unmodified Oriental beech.
