Porovnání hydrotermické a chemické plastifikace dřeva
 Rousek, Radim
The process of wood plasticization and densification has been known for decades. It is used for improvement of mechanical properties of low density wood. The objective of this study is to compare two different methods of wood plasticization. Specimens made of European beech wood (Fagus sylvatica) were plasticized by hot steam or gaseous ammonia and then compressed in tangential direction. Stress-strain behaviour during compression was evaluated. In this study influence of growth ring angle on densification process was also investigated. Gaseous ammonia at a pressure of 0.2 MPa was less efficient than hot steam. The best plasticizing effect was reached by combining these two methods. A growth ring angle of 15° from direction of compression (almost tangential) was evaluated as the best for densification of European beech wood.

Posouzení možnosti využití buku v materiálech na bázi dřeva a ve výrobcích
 Horníček, Stanislav
The thesis deals with the assessment of the possibilities of using wood in wood-based materials and products. Part of this thesis is a list of basic wood-based materials used in timber construction. Furthermore, assessment of possibility and explanation of wood modification principles. The thesis includes the design of functional element of the product and also experiment examining selected physical properties of the modified beech wood. The aim is to create a basic overview of trends in production, products and in the use of wood-based materials and possibilities of the use of beech wood for these products and materials.
