Multiobjective Optimization in EMC
Olivová, Jana ; Sekanina, Lukáš (referee) ; Křesálek,, Vojtěch (referee) ; Raida, Zbyněk (advisor)
The work is aimed to propose a methodology for creating an equivalent of composite materials used for construction of small aircraft. Such equivalent should enable to create numerical models of small aircraft in the simulation of precertication EMC tests for aircraft resistance against the lightning. Eliminating situations threatening the aircraft and passengers in the initial steps of the design will allow savings in production costs and contribute to the safety of air transport. In order to nd the equivalent of composite materials, global optimization methods will be used.

Efficiency Improvement Concept of Production of Rotary Component
Trčka, Radim ; Slaný, Martin (referee) ; Sedlák, Josef (advisor)
This diploma thesis deals with machining of rotating components made of composite material. Components of the two manufacturing technologies are compared. The aim of the thesis was to analyze and calculate the costs of the given technologies for different production batches. At the end of the diploma thesis there is a technological-economic evaluation and decision on which production technology will be used.

Design of laminate handlebars for mountain bikes
Hanák, Jiří ; Ševeček, Oldřich (referee) ; Polzer, Stanislav (advisor)
This bachelor’s thesis describes design of laminate handlebars for mountain bikes. The first part describes the mechanical properties of composite materials, with the emphasis on fiber composites. The algorithm for acquiring material characteristics of fiber composite by analytical method is presented. In the next part, it is shown how to control the direction of fibers in lam-inate in the finite element calculations and its impact to resulting stresses in the material. The aim of the last part is design geometry model of laminate handlebars for mountain bikes with following stress – strain analysis by FEM and software ANSYS. The analysis is performed for static loading.

Cement-bonded particleboards with utilization of alternative raw materials
Urbánek, Libor ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
The diploma thesis is focused on effective utilization of currently produced alternative raw materials in the production of cement-bonded boards. The emphasis is primarily on the scraps and dust arising from the processing of cement-bonded slabs, as well as on slag and limestone. The theoretical part contains a survey of current knowledge about the given issue. In the experimental part, the alternative raw materials were analyzed in detail and their influence (as modifier components of the matrix and the filler) on the properties of cement-bonded slabs was examined. Research and development took place using physico-mechanical, thermal and microstructural methods.

Technical documentation of parts made from composite materials
Vlček, Dalibor ; Urík, Tomáš (referee) ; Klement, Josef (advisor)
This bachelor thesis describes the rules applicable for creation of technical documentation of parts made from composite materials. In the first part of this paper a brief characteristics of composite materials is introduced. In the subsequent parts the thesis deals with the basic principles of creating the documentation according to the European standard EN 4408. The main aim of this thesis is to summarize the rudimental conventions that refer to drawing of technical documentation of aircraft composite parts.
