Wood is a natural polymeric material widely used in construction, joinery, furniture, etc. Many applications of wood require that the material is previously dried to a defined level below the fibre saturation point. During drying, however, the structure and properties of wood are modified. In this book, the three main mechanisms that occur during drying are presented and their effects on the structure and properties of wood are discussed. Understanding the effects of such mechanisms should provide a basis for developing wood drying methods that improve the performance of dried wood products. This book will be of interest to researchers and professionals in the field of wood science and technology, as well as to wood craftsmen and enthusiasts.
