Mechanical properties of Nodular Cast Iron prepared by method Tundish and process Initek
Vítek, Radovan ; Hotový, Ivan (referee) ; Věchet, Stanislav (advisor)
This bachelor thesis deals with a properties and production of nodular cast iron. The first section describes the classification, distribution and structure of nodular cast iron. The second part is focuses on the description of nodular cast iron, modification, inoculation and production. A strong effort is made on the production of nodular cast iron using the Tundish Cover method and the Initek process. In conclusion, the structure of the material is evaluated on samples that were delivered for metallographic analysis. The final evaluation of the structure of the material is used to compare the mechanical properties of a nodular cast iron produced by Tundish Cover method and Initek process.

Production Possibilities of Press Brakes
Hrazdíra, Michal ; Jopek, Miroslav (referee) ; Řiháček, Jan (advisor)
The bachelor thesis deals with the production possibilities of press brakes. This is a literary research, in which the aim of the work is to describe the principle of bending. It also focuses on common and special tools and their use in engineering practice. The first part of the work is focused on general bending technology, which discusses the basic principles and possibilities of this method. The main chapter is the bending itself, where the individual types of machines, their components, tools and clamping systems are introduced and described. Furthermore, modern tools and their application in engineering practice are presented. In the last part, the production of the switchboard cabinet is presented on a CNC press brake.

Application of FRP reinforcement in the design of concrete structures
Kratochvílová, Barbora ; Lagiň, Juraj (referee) ; Girgle, František (advisor)
This bachelor thesis deals with two types of reinforcement FRP reinforcement and generally used steel reinforcement. The first part of this thesis is focused on theoretical knowledge related to FRP reinforcement. There is described its composition, properties, production, durability and its design properties from a theoretical point of view. In the following part, the design and assessment of a specific prefabricated U part is performed. The design and assessment is performed in two variants from FRP reinforcement and steel reinforcement.

Thermal aging of nanocomposites
Janíček, Martin ; Rozsívalová, Zdenka (referee) ; Polsterová, Helena (advisor)
This thesis deals with issues of properties of nanocomposites and it´s heat aging. In the first part there are theoretically analysed some of the basic therms connected with nanocomposites. Also there are outlined basic methods of production of these matherials. The most important is specification of individual properties when bigger attention is gived to electrical properties. Practic part deals with heat aging of samples of nanocomposites filled with nanoparticles Al2O3. There was monitored impact of time of aging on values of internal resistance, dissipation factor and relative permitivity.

Design of composite prosthetic appliances production technology
Magula, Martin ; Slaný, Martin (referee) ; Zouhar, Jan (advisor)
This bachelor thesis deals with the topic of manufacturing a composite prosthetic arm. The first part of the thesis is devoted to the research of basic composite materials and technologies for the production of prosthetic devices. The second part of the thesis is focused on the practical manufacturing, where from the scanning of a previously made prosthesis we obtain a model. Following this part, a part of the arm will be fabricated and subjected to material testing.

Bonding of composite materials in precise applications
Hartmann, Kurt ; Gregor, Lukáš (referee) ; Kupčák, Radim (advisor)
A study on composite materials and adhesive technology was conducted as part of the research. The main objective of the work was to evaluate the suitability of selected adhesives for precision applications. The practical part focused on this objective and included the design and development of a special bonding preparation, enabling the creation of samples for subsequent strength testing.
