Composite boards and other materials that are used in the production of furniture must be characterized by the proper bending strength and modulus of elasticity and according to Smardzewski (2019) these parameters are crucial for this branch of industry. The example combining good mechanical features and low density can be the panels which are produced by pressing shavings and waste sawdust parallel to the direction of tunnels (Drouet 1992). They are an excellent response to the current market needs due to the fact that they are made of materials considered as waste and the presence of tunnels in the board makes the weight much lower in comparison with the solid particleboards. Therefore, the aim of the presented work was to develop and innovative three-layer lightweight composite board with a core layer similar to tubular chipboard made of sawmill wastes such as sawdust not subjected to sorting.
Keywords: chipboard, mechanical properties, glued elements
