The thesis deals with the influence of veneer perforations on the strength of the bonded joint. The main aim of the thesis is to find out how the spacing and orientation of perforations and veneer orientation influence the bonded joint. To meet the target, it is necessary to produce two- and three-layer lamellas using LDPE foil for bonding. The thesis is divided into three main parts. The first part explains the theoretical knowledge that is directly related to the issue. The second part is devoted to the preparation and production of individual test bodies, but also to the experimental part, where the methodology of individual tests is analyzed. In the last, third part, the evaluation of the results of the performed tests and the summarization of how specific factors affect the strength of the bonded joint are discussed. The results were produced through tables and graphical illustrations. As a result, we have shown that veneer perforations have a rather significant impact on the bond strength. The negative is that the perforations do not have a positive effect but a negative effect.
