Additional reinforcement of wood elements
Janoušek, Radek ; Vejpustek,, Zdeněk (referee) ; Vaněrek, Jan (advisor)
This diploma thesis deals with the possibilities of additional reinforcement of wooden elements using different types of BFRP materials. In the practical part, an experiment of reinforcing plywood with external reinforcement using BFRP fabrics with different basis weights was performed. As part of the strength tests performed, the specimens were subjected to bending and shear stresses. To verify the bonding quality of the plywood, the bodies were exposed to the effect of elevated temperature and a delamination test was performed to determine the bonding quality of the plywood joints. The achieved values were evaluated and compared with the available literature.

Development of wood-based board materials applying thermal modification process
Buriánek, Vlastimil ; Pipíška,, Tomáš (referee) ; Vaněrek, Jan (advisor)
This diploma thesis deals deals with the effectiveness of polyurethane and phenol-resorcinol-formaldehyde adhesives when applied in bonded joints of thermally treated sheet materials. The thermal resistance of commercially used adhesives was analysed as part of a research activity. Furthermore, the changes in the properties of wood materials after heat treatment were described. In the practical part, the effectiveness of the used adhesives on densified birch plywood was verified with respect to the shear strength of the resulting composite. Based on the results obtained, it was proceeded to verify the effectiveness of densification on spruce plywood.
