Surface Hardness Improvement of Larch Wood Using Thermal-Compression

This study was conducted to investigate the surface hardness of thermally-compressed larch wood by compression set and temperature. The surface hardness of thermally-compressed larch wood increased with increasing compression set and temperature. For compression set 60%, the specific gravity was increased as 0.93. However, the surface hardness was lower value as 31.1 N/mm2 compared with a similar specific gravity of the tropical timber. For density pro-file, less than compression set 40%, compression was observed mainly surface area. On the oth-er hand, more than 50%, density profile variation was reduced by compression of central part. Results of this study indicate that thermally-compressed larch wood can be replace some im-ported hardwoods such as oak or cherry. However, thermally-compressed larch wood was diffi-cult to replace the tropical timber being imported in terms of surface hardness.
