Abstract
The influence of structure on selected properties of a lignocellulosic composite. As part of the research, the influence of the number of layers and the structure of plywood on selected physico-mechanical properties was determined. The scope of work included: bending strength and modulus of elasticity, resistance at axial removal of screws and density profile. The influence of thickness increase on selected properties of plywood was confirmed. Flexural strength decreases by 60%, modulus of elasticity by 71%. As the number of composite layers increases, the screw holding capacity increases by 33%. Density oscillates around the value of 650 kg / m3, possible deviations occur through the influence of the anatomical structure of wood and glue joints.
