Özet
The Finnish wood heat treatment technology, ThermoWood, was recently introduced to Turkey. Data about the mechanical and physical properties of Turkish woodspecies are importantforindustry andacademia. In this study, two industrially important Turkish wood species, pine (Pinus nigra Arnold.) and fir (Abies bornmülleriana Mattf.) were heat-treated using the Thermo Wood process. Pine and fir samples were thermally modified for 2 hr at 212 and 190°C, respectively. The modulus of rupture (MOR), modulus of elasticity in bending (MOE), impact bending strength (IBS), and compression strength (CS), in addition to swelling (Sw) and shrinkage (Sh) of thermallymodified wood were examined. The results indicate that the heat treatment method clearly decreased the MOR, MOE and IBS of pine and fir. However, a small increase was observed for CS values of heat treated wood species. The most affected mechanical properties were MORandIBS forboth pine andfir. The reduction in MOEwas smallerthan that in MORandIBS. Volumetric shrinkage andswelling of these specieswere alsoimproved'byapproximatelyhalf. In addition, the changesin the mechanical and physical properties studied in pine were larger than that of fir. © Triveni Enterprises, Lucknow (India).
