Özet
The Finnish wood heat treatment technology Thermo Wood, was recently introduced to Turkey Data about the mechanical and physical properties of Turkish wood species are important for industry and academia. In this study, two industrially important Turkish wood species, pine (Pinus nigra Arnold.) and fir (Abies bornmulleriana Met) were heat-treated using the Thermo Wood process. Pine and fir samples were thermally modified for 2 hr at 212 and 190 degrees 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 thermally-modified 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 MOR and IBS for both pine and fir. The reduction in MOE was smaller than that in MOR and IBS. Volumetric shrinkage and swelling of these species were also improved by approximately half. In Addition, the changes in the mechanical and physical properties studied in pine were larger than that of fir
