Kompozitní materiály a jejich užití v dopravní technice
ZEMAN, Tobiáš
This bachelor thesis is divided into theoretical and practical parts. The theoretical part deals with composite materials themselves, their types, production technologies and especially their use in transport technology. In the practical part, an experimental test of tensile and flexural strength was carried out on carbon fibre samples in order to compare the resulting values. The tensile strength was found to be many times higher than the flexural strength.

Optimized manufacturing of aluminium castings by using lost wax technology
Talanda, Ivan ; Horenský, Jiří (referee) ; Horáček, Milan (advisor)
Aim of this diploma thesis is to choose new pattern wax for Fimes a.s. foundry. New wax should substitute old not fully satisfactory pattern wax which caused problems in technological process resulting in increased number of rejects. New pattern wax should eliminate current problems and help foundry with producing large, thin-walled, high-quality castings. Numbers of pattern waxes supplied by world’s leading wax manufacturers were subjected to laboratory tests and pilot study. This diploma thesis is part of project Alfa TA01010766: „Research and development of production technology large, thin and high quality castings of aluminium alloys “

A new design and technology of the low-pressure output part
Sláma, David ; Slaný, Martin (referee) ; Píška, Miroslav (advisor)
The aim of this work is make a new design and technology of the low-pressure output part of rail which is made in BOSCH DIESEL s.r.o. company. In the thesis is analyzed in detail the bending test, which is part of the quality control of the low-pressure welding joint. In the next part of the thesis is proposed the process of machining of this component, followed by experimental finding of welding parameters for resistance welding. Then several pieces are welded, which are measured and tested. The results of this tests are compared with customer requirements. Finally, a technical and economic evaluation of the change is made, which will save a considerable amount of money for the company.
