Wood is increasingly used in the construction sector since it is environmentally friendly and cheap. To meet the high demands, accurate knowledge of wood and its properties is necessary. Thereby wood water relations are of great importance, due to the pronounced influence of moisture and moisture changes on mechanical properties as well as on dimensional changes. Nevertheless, the formulation of an accurate model for moisture transport in wood is a challenging task, which has motivated a lot of research effort. Moisture transport in wood is a diffusion process. This article provides an overview of molecular diffusion and permeability in wood. The recent developments in the formulation of models for moisture transport in wood and characterization of moisture content in wood are also presented. |
