Influence of technological factors on the hardness of wood
Šafaříková, Lenka ; Gašparík, Miroslav (advisor) ; Ruman, Daniel (referee)
Focus of the diploma thesis is to investigate the influence of the selected factors (type of wood, thickness, densification) on the wood hardness. For the experimental measurements the Brinell hardness test method was used. The hardness measurements were performed on the specimens made from two different types of wood. Obtained results were statistically analyzed into the graphs. The main goal of the thesis was to determine the change in the static hardness in dependence on the previously mentioned factors. From the experimental data it can be seen that the wood hardness increases with the higher degree of densification . This phehomenon applies to both investigated wood materials which are European beech (Fagus sylvatica) - hardwood specimen and European aspen (Populus tremula) - softwood specimen.
