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.

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.

Use of FRP Composites as Reinforcing Material for Concrete
Kratochvílová, Denisa ; Prokeš,, Jan (referee) ; Bodnárová, Lenka (advisor)
Because FRP composites have high fiber strength and good durability, they are increasingly used for repairs, modernisation and reconstruction of concrete structures. In practice, however there is a risk of premature separation of FRP reinforcement from concrete. This can be avoided by appropriate selecting the fibers and the matrix and the appropriate shape of the reinforcement. The actual materials and consistency of FRP reinforcement with concrete are also covered by this diploma thesis.

Composite materials and their use in sport
PÍSAČKA, Petr
This bachelor's study pursues the utilizing of modern composite materials in spor-ting sector. It is processed as an instructional text which could be used as a supportive or supplemental subject matter for materials and technology. The study is divided in two main parts which are further sectioned into subchapters. In the introduction of the first part of the bachelor's study the development of composites is explained during the human history. Following chapter mentions the basic characteristics of the composites and presents various definitions of the composites and the term of synergic phenomenon is clarified. The next chapter discusses the most im-portant matrices based on the plastic materials which are divided into reactoplastic ma-trices and the thermoplastic ones. The features of the particular materials and their use in the production are integral part of this study as well as the illustrative pictures. The second part of this bachelor's work is focused on the practical use in the spor-ting industry namely in sporting aviation, skiing, archery, bicycling, canoeing, soccer and to manufacture hockey sticks. The production, practicability, advantages and the imper-fections are stated here as well. The chapter after that shows the price ranges of the abo-ve mentioned sporting equipment in comparison with the conventional and composite materials. The part of the second chapter is about the future of the composite materials and their current and future utilizing. In connection with the future of the composite mate-rials the use of natural fibers are mentioned too.

REBALLING OF BGA PACKAGES USING PACE TF2700 EQUIPMENT
Roháček, Peter ; Špinka, Jiří (referee) ; Starý, Jiří (advisor)
The Diploma thesis is focused on reballing of BGA packages with the device PACE TF 2700. It describes the general types of BGA packages, their defects, importance of thermal management to the solder techniques, where it is also talked about the meaning of solders and fluxes for the joint. The work informs about the most common methods of reballing, the proper handling of components and the current situation with BGA stencils on the market. It briefly describes the device operation of PACE TF 2700, that is working on the convection and IR principle of heating components. It deals with the manufacturing of the template, dummy BGA packages, the test plates, creation of the thermo profile, comparing and examining the defects and their causes, which had the most significant impact on the results. The achievements would serve for comparing them with the results of the future laboratory exercises or as a subject for further works.
