INFLUENCE OF TEMPERATURE ON CRACKING AND MECHANICAL PROPERTIES OF WOOD DURING WOOD DRYING – A REVIEW

Laura Oltean, Alfred Teischinger, Christian Hansmann

Abstract


The occurrence of cracks and loss of mechanical properties are major problems in wood drying, and careful control of drying conditions is necessary in order to avoid this form of defects. Wood drying at different temperatures, especially high temperatures, has gained much interest in the last several decades. Some solutions for minimizing drying defects, such as cracks and decrease of mechanical properties due to the increase of drying rates, decrease of drying time and thus cost, must be acknowledged and understood. The present review tries to summarize the influence of temperature during kiln drying on the mechanical properties of wood and on the occurrence of cracks.
