The diploma thesis is focused to testing and evaluation of two-layer bonded wood materials under impact stress. The thesis is created from four chapters. In the fist chapter we have focused to theoretical points, we characterized bonded wood materials in composite materials. In the second chapter we defined the aims of diploma thesis. In the third chapter is described methodology of thesis, charakterized the materials used for testing samples and specified all testing samples used during testing of impact stress on wood. In the same chapter is also describes and explained the method of testing impact strees using pendulum hammer. The fourth chapter is focused to the evaluation of results to testing of wood materials under impact stress and is supplemented with pictures and statistics of testing materials. The result of this diploma work is a comparison of two-layer glued wood-based materials and evaluation of the best material combination for the used applied load.
