The diploma work is focused on the development and analysis of plywood material reinforced by means of synthetic fibers, namely on its mechanical properties in a three – point bend in compliance with the CSN EN 310 Standard in comparison with the conventional plywood. At first, the mechanical properties of the material were simulated with the aid of a computer-aided model on the basis of the classical laminate theory and then compared to the real measured values. In addition to it, the influence of preloaded fibers on the mechanical properties of the composite was examined. To preload the fibers, two simple fixtures were manufactured. The analysis of variance and the Tukey’s test of multiple comparison demonstrated important differences in the resistance and rigidity of the plywood material both with the reinforcement and without it. The highest resistance proved the plywood samples without any reinforcement (at an average of 153.9 MPa), the highest rigidity was achieved in samples with reinforcement without any preloading (at an average of 29374.4 MPa).
