Application of a reusable vacuum membrane for production of fiber reinforced plastics
Talavášek, Václav ; Zouhar, Jan (referee) ; Gregor, Lukáš (advisor)
The thesis focuses on the manufacturing process of the composites with fiber reinforcement and polymer matrix. The theoretical part contains a description of conventional manufacturing processes. The experimental part of the thesis was based on the design modification of an old convention mold. The aim was to make design changes for the usage of a vacuum membrane. On the mold were made several tests. The goal was to find out the design faults of the mold. The next chapter focuses on the economic comparison of the conventional process and the reusable vacuum membrane process. The last chapter focuses on the design of a new mold, which is going to be utilized for mass production.

Method for evaluation accuracy of milling robots
Cabalka, Jan ; Slaný, Martin (referee) ; Zouhar, Jan (advisor)
This thesis describes the design of methodology for measuring the accuracy of robot machining. It describes the theoretical properties and classification of commercially available methods for precision measurement. In the practical part, a test workpiece is manufactured and positions and toolpaths are measured by the Pontos system. The proposals are based on the MCAE Systems company's equipment.

Bonding of composite materials in precise applications
Schubert, Vojtěch ; Zouhar, Jan (referee) ; Kupčák, Radim (advisor)
This work is focused on the bonding of composite materials. Related research dealing with technology of production and bonding of these materials was additionally conducted. Practical part of this thesis was set to find out what the optimal bond line thickness was for the bonding of the composites. Thus, the strength of single-lap joints (SLJ) in series of various bond line thicknesses was therein tested. A model of samples (and design of their production by wet lay-up) for the experiment is also provided in this thesis.

Technology of manufacturing of carbon fibre composites by hot forming
Přikryl, Pavel ; Slaný, Martin (referee) ; Zouhar, Jan (advisor)
This master’s thesis deals with the composite materials and especially aims on the carbon and glass fiber composites. It points out different composition types and manufacturing methods which reflect in the different mechanical properties, final quality of the manufactured part and also in the manufacturing time. The practical part includes two particular manufacturing methods using prepregs, one cured in an autoclave and one by hot compression moulding.

Robotic machining of composite materials
Rubišar, Václav ; Sedlák, Josef (referee) ; Zouhar, Jan (advisor)
This thesis deals with the robotic machining of composite materials. It is divided into two main parts - theoretical and practical part. The theoretical part is focused on detailed introduction of the term “an industrial robot” and a description of its controls, types of the robots, types of their propulsion and programming methods. Furthermore, there is a list of CAM softwares with its specification designed for both conventional machining and machining by using a robot. It also includes the introduction of composite materials and specification of their machining. The practical part deals with selection of appropriate type of bracket spindle by using a simulation software, suction design and economic evaluation of two types of machining in manufacture.
