Wood Physics

The research focuses on studies of physical properties of wood, especially moisture related properties and how these are affected by drying and heat treatment. Also, process technology, control systems and microwave heating and drying are included. As research tools we are using X-ray computed tomography and SEM as well as image analysis and multivariate statistics.

We are experimentally oriented and application oriented in our research approach. Today we have new CT scanner which is used in combination with a unique climate chamber. This method allows non-destructive measurements of density variations and is thus particularly suitable for in situ studies of moisture flow in wood during drying and heat treatment. It is also possible to monitor the dimensional changes during the process, and internal or surface checking.

Our research over the years has led to the development of industrial drying techniques such as using water vapor for heating and conditioning. We have also initiated adaptive methods for process control of batch drying, a technique now used in a wide range of industrial kiln dryers. Our latest area of ​​research involves the modification of wood with different methods such as thermal modification or oil impregnation. The performance of the wood is influenced by such treatment including resistance to biological degradation, improved dimensional stability, mechanical properties and sorption behavior.


The goal of our research is to determine the wood materials physical and chemical properties and how these are affected by industrial processes and exposure to climate from forest to the final product. Ultimately, we want to pursue the objectives of the renewable raw materials such as wood, can be used in more applications than it is today.


For this research we have access to an X-ray computed tomography with climate chamber, scanning electron microscope SEM, DMTA equipment and tensile testing machine which enables materials studies from micro to macro level.We also have equipment for certain chemical analysis such as FTIR, HPLC and GC-MS.
