Návrh skladby materiálu na bázi dřeva s protipožárními vlastnostmi
 Linhart, Vladimír
The topic of my thesis was to create the optimal composition of wood-based material with fire-resistant ability. Proposed material will be mainly applied on the front doors. There was a research done on different kinds of adhesive. The glue was tested for its quality of the glued joints and bonding strength of the composite wood-based material according to the required valid standards. Based on the test results suitable glue was chosen. There was also a research done on wood-based and non-wood-based composing materials along with insulating materials. The research was focused on the material suitability and ability to be applied on constructions of fire-resistant sandwich front door kits. Test for fire resistance according to ČSN EN 1634-1 was conducted on chosen product, followed up by certification of this product. Furthermore, the certification according to ČSN EN ISO 6946 using ČSN EN ISO 10077-1, ČSN EN ISO 10077-2 and thermal transmittance of the front doors with plain door wings according to ČSN EN ISO 10077 was carried out. Subsequently the new product was put into practice and was included in new production list.

The overview and the evaluation of the technical specifications of transparent materials for the production of composite wood panels
 Holub, Jan ; Böhm, Martin (advisor) ; Arnetová, Karolína (referee)
Work includes: general introduction to the components of the wood-based panels with a transparent layer, the history of their production. It includes requirements for individual components of composite wood panels and requirements for wood and other wood-based materials, which serve as reinforcement. Also mentions claims potting material, which serves as a matrix. It includes a description of the technology of wood-based panels with a transparent layer. This paper introduces the most commonly used material serving as a matrix, their distinctive characteristics essential for the production of composite plates. Compares parameters resins based on polyester, polyurethane and epoxy resins and analyzes the choice of a suitable material for producing a composite board based on user requirements. Part of this work is to design materials for the manufacture of composite board with controlled light distribution.

Porovnání spotřeby času a materiálu u vybraných elementů schodiště
 Šot, Jan
This thesis compares the time consumption and financial requirements of production of selected stair elements of several materials. Time consumption is define by actual measurement of the work specified for the elements of the boards and the elements of fibreboard finished by lacquer and finished with veneer and lacquer.Tables with values of partial operations performed on basic carpenter tools and with combination of CNC machinbes are worked out in this thesis.
