Design of manufacturing technology for motorcycle headlamp body
Nosek, Jan ; Urbanec, Antonín (referee) ; Kandus, Bohumil (advisor)
The thesis is a proposal technology of the main body of motorcycle polymer material from Bayer's APEC - high temperature polycarbonate 1703. Literary study summarizes findings from a thermoplastic injection molding technology and the possibilities of structural design of injection molds, plastic plating technology from a focus on the most important technology in the field of lighting technology vehicles. Given the anticipated production run of 50 thousand. pieces are assessed a total of 2 variants of the molding parts. The practical part was modeled and specified product designed mold. Construction was done by using SolidWorks 2007 software and normalities FCPK Bytów and HASCO. For the selected option is implemented technological calculations. For the proposed technology was chosen Allrounder injection molding machine 570 A the manufacturer Arburg designed and suitable technological process of production.

Degradation possibilities of synthetic macromolecular materials centred on biodegradations
Zichová, Miroslava ; Ondruška, Vladimír (referee) ; Babák, Libor (advisor)
This work deals with the degradation possibilities of synthetic macromolecular materials. Mechanical, chemical and chemo-physical degradation is described, but the work is focused on biodegradation. Polymer biodegradation is its decomposition by microorganisms. The aim of the work is to show the advantages of biodegradation and to arrange the knowledge acquired about the biodegradation of particular macromolecular materials. There is resumed the information about the degradation of polyurethanes as an exception among synthetic polymers, which are mostly resistant to biodegradation. Attention is also paid to biodegradable polymers.

The influence of conditioning on the mechanical properties of polymers produced by injection molding technology
Neužil, Tomáš ; Řehořek, Lukáš (referee) ; Válka, Libor (advisor)
The aim of the thesis is to determine change of mechanical properties of three types of damp polymeric materials (polyamides) depending on the water content inside material. Before testing, specimens of all three types of materials were placed inside the air conditioning chambers until equilibrium (conditioned) state was reached when the specimens received the maximum possible amount of water from the environment. A total of three conditioning levels were set, representing besides the standard level of conditioning both extreme states like state when the material was fully dried and the state where the material content the largest possible amount of water. With the increasing content of water bound in material, there is a characteristic change in the mechanical properties of the material, such as a decrease in strength and modulus of elasticity and an increase in toughness and ductility. To examine material properties change, tensile and Charpy impact tests were performed, Charpy impact tests were performed for both specimens with and without a notch. Besides changes in mechanical properties, the rate of water absorption was also observed depending on the materials and its filling.

Testing of Surge Arresters
Jeřábek, Lukáš ; Paar, Martin (referee) ; Krbal, Michal (advisor)
This bachelor's thesis is devoted to metal oxide surge arresters. After historical and theoretical introduction, which explains their principles and describes their characteristical properties, analysis of the standard IEC 60099-4 and testing according to the standard with focus on the type tests follows. This chapter is also amended with review of the standard's imperfections and with its most probable future development. The work concludes with a market survey, a review of the largest manufacturers and a comparison of their products.

Optimization of Material Plastification Process
Šeniglová, Hana ; Krpoun, Karel (referee) ; Pantělejev, Libor (advisor)
This bachelor´s thesis deal with the optimization of the process of material plastification. The purpose of the thesis is to devise feasible parameters of a injection molding machine. The goal was achieved by the „Design of Experiments“ method. The necessary measurements were taken on the sample, a filter fuel tank, which was provided by the company Robert Bosch České Budějovice. Each measurements are described in the bachelor´s thesis. The results are summarized and evaluated in the Minitab software used for optimal parameters settings of the production process.

The study of utilization of raw materials based on glass recyclate
Bajer, Tomáš ; Čermák, Jan (referee) ; Šťastník, Stanislav (advisor)
Presented work deals with the problem of solar glass waste recycling. In theoretical part recent EU regulation regarding waste management is presented. Different ways of PV panels recycling are explained as well as raw materials for glass production are listed. Differences between regular and solar glass is explained. In experimental part different recipes using solar glass waste and polymer binders are presented. Grindability was tested on specimen tiles. Potential of solar glass waste for manufacturing products with acoustic properties was examined.
