Density and some mechanical properties of densified and heat post-treated Uludağ fir, linden and black poplar woods
The effects of thermo-mechanical densification and heat post-treatment on air-dry density, modulus of elasticity (MOE), bending strength (MOR), and compression strength parallel to the grain (CS) of Uludağ fir ( Abies bornmulleriana Mattf.), linden ( Tiliagrandifolia Ehrh.), and black poplar ( Popul...

| description | The effects of thermo-mechanical densification and heat post-treatment on air-dry density, modulus of elasticity (MOE), bending strength (MOR), and compression strength parallel to the grain (CS) of Uludağ fir (
Abies bornmulleriana
Mattf.), linden (
Tiliagrandifolia
Ehrh.), and black poplar (
Populus nigra
L.) wood samples were investigated. Samples were densified with compression ratios of 25 and 50%, and at 100 and 140 °C. Then, the heat treatment was applied to the samples at 185 and 212 °C for 2 h. According to the results of the study, density of all wood samples increased together with the increase of compression ratio. Regarding compression temperature, the highest density increase was obtained at 100 °C. Mechanical strength (MOE, MOR, and CS) in densified samples increased depending on compression ratio and increase of density. The highest strength increase was in black poplar samples and the lowest was in linden samples. After heat post-treatment, mechanical strength of samples decreased depending on increase in treatment temperature. However, strength values (MOR except) of samples which are 50% compressed and heat-treated were found higher than control samples. |
