Thermally Compressed Poplar Wood (TCW): Physical and Mechanical Properties
Korkut, Suleyman/0000-0002-4871-354X ; WOS: 000321163600004 ; Various thermal modification techniques are used to improve some properties of wood materials. Thermally compressed wood (TCW) is obtained by using a hot-press. This study investigates the effect of thermal compression on the density, vertical density profile (VDP), moisture content (MC), thickness swelling (TS), Janka hardness, and drying characteristics of the poplar wood boards. The experimental boards were cut from poplar wood (Populus spp). The boards with dimensions of 100 mm by 500 mm by 25 nun were thermally compressed at press temperature of either 150 degrees C or 170 degrees C, press pressure of either 1 or 2 MPa for 45 minutes in a hot-press. A total of 10 experimental boards were prepared - two boards for each group plus two for control. The results obtained in this study indicated that the density and Janka hardness values increased with the increase of the press pressure. The thermal compression process decreased the thickness of the boards. The thickness reduction increased with the increase of the press pressure. An improvement was not seen in the TS values of the samples when compared to those of the untreated samples. This study revealed that the thermal compression technique should be used to improve some properties of poplar wood. In this way better use could be made of low-cost poplar wood. ; Istanbul University Research FundIstanbul University ; The authors thank Istanbul University Research Fund for its financial support in this study. The authors would also like to express their appreciation to Kastamonu Integrated Wood Industry and Trade Inc., Kocaeli, Turkey for their assistance and Kerem Salih Colak, Huseyin Basri Bayirli and Osman Zafer Kaya, who are former undergraduate students at the Department of Forest Products Engineering at the Istanbul University, for their valuable help during the testing procedure. This article is an extension and continuation of the study presented at the ICWSE 2011 Conference.
