The main purpose of this study was to investigate mechanical properties
such as the modulus of rupture (MOR) and compression strength parallel
to grain (CSPG) of impregnated and heat-treated Oriental beech (Fagus
orientalis L.) wood. Some copper and boron containing impregnation
chemicals such as Wolmanit CX-8 (WCX-8) and Celcure AC-500 (CAC500) were used. Wood specimens were impregnated 2% aqueous solution
of the chemicals according to ASTM D1413-07e1 standard. The wood
specimens were heated at 150 and 175 °C for 4 and 8 h, respectively.
Results showed that both impregnation and heat treatment decreased the
MOR and CSPG of Oriental beech wood. The MOR losses of Oriental
beech after both treatments were higher than CSPG losses. The largest
reduction of MOR and CSPG were observed with 51.5% and 15.5% for
CAC-500 impregnated and heated at 175 °C for 8 h. Except for WCX-8
impregnation and heat treatment at 150 °C for 4 and 8 h, the MOR values
of impregnated and heat-treated Oriental beech wood were lower than
only heat-treated Oriental beech wood. It was also found that the CSPG
values of impregnated and heat-treated Oriental beech wood were higher
than only heat-treated Oriental beech wood, except for impregnation and
heat treatment at 175 °C for 8 h.
