Cellular wood material properties – review

The invention of cellular wood material and lightweight furniture panels with the trade mark of Dendrolight® is just one of the wood industry’s innovations in the last decade. During the manufacturing process due to the sawn longitudinal grooves, solid timber becomes 40% lighter. Timber with grooves is a raw material for the cellular wood material production and furthermore is used for various sandwich panel designs. Since 2007 when cellular wood material production technology and furniture panels were patented, several researchers worked with experimental, analytical and numerical analysis of the cellular wood material properties for structural applications. This paper summarizes the main knowledge about the physical and mechanical properties of cellular wood materials and the possibilities for their potential improvement.
