Course Description

PHYSICAL & CHEMICAL PROPERTIES OF WOOD The field of Science and Technology of Wood is very broad. The progress made and the prospects for the future are based on the fact that wood is the object of great scientific and technological interest, the purpose of which is to acquire a better knowledge of the structure and properties of this material. These topics are now taught in universities and occupy researchers in most countries. Very important progress has been made, mainly with research conducted in forestry schools and forest products laboratories. It may be said that the study of wood started in ancient Greece with Theophrastus, a student of Aristotle; however, for a very long period of time only macroscopic and empirical observations could be made. Microscopic structure was studied after the invention of the microscope, and the first studies of properties were made in the eighteenth century. Today, all means of modern research are employed in the study of wood, but progress in the field of utilization is also related to the general advancement of technology (Tsoumis, 1991). In order to understand the reason for scientific interest in wood, one must take into consideration that this material produced and consumed in very large quantities, which are expected to increase in the future. To meet such demand, it will be necessary to increase wood production from the forest and to improve its utilization.
