MECHANICAL WOOD MODIFICATION METHODS
The wood material has been the most preferable material in order to meet the needs of accommodation, transport and social since human beings existed. The different “Wood Modification Methods” has been developed as a result of all the scientific studies and researches in order to remove the negative characteristics of the wood material from centuries ago to nowadays. The wood material is usually admitted as too soft and too weak for structural applications required hardness and durability. However, the wood material increased density can be an alternative for other structural materials. Most of the wood material mechanical characteristics are related to density. A lot of studies have been carried out to develop the suitable operation, because the densification of wood material increases mechanical characteristics and hardness of wood material. By means of densification, low-density wood material is converted to high-density wood material, and its trade value is increased. In this study, from the environment friendly modification methods which is used to modify wood material and to improve mechanical strength properties of wood Thermo-Hygro-Mechanic (THM), Viscoelastic-Thermal-Compression (VTC), Thermo-Mechanic (TM) and the new application Thermo-Vibro-Mechanic (TVM) have been investigated.
