Vliv impregnace přírodní a syntetické pryskyřice na vybrané mechanické a fyzikální vlastnosti bukového dřeva
Syrovátko, Jakub
The aim of this thesis was to analyze the influence of natural synthetic resins impregnation on selected material properties of wood. Beech (Fagus sylvatica L.) wood used in present study, as a wood species considered as easy to be impregnated. Specimens with dimensions of 20 × 20× 30mm were vacuum impregnated by natural and synthetic resins at 20 kPa for 1.5 hours. Afterwards, the weight percentage gain (WPG) was evaluated and modulus of rupture (MOR) and modulus of elasticity (MOE) in compression parallel to the grain were experimentally determined. Obtained data sets were statistically analyzed and results were discussed and compared to relevant literature.
Pružnostní a pevnostní charakteristiky lepeného nosníku využívajícího recyklovaného dřeva
Syrovátko, Jakub
The subject of the thesis was the analysis of recycled wood for the use of glued beams on selected mechanical properties. Recycled wood was used for this research. Test specimens, ie lamellas with dimensions of 2000 × 80 × 20 mm, were made of both recycled wood and healthy wood, which was subsequently glued into a laminated beam, always after an odd number of layers; 2000 × 80 × 100 mm. Subsequently, values of tensile strength and modulus of elasticity in cross-fiber compression were determined experimentally. The measured data were statistically analyzed and the results discussed and compared with the literature.
