Design of the extruder for 3D printing the composite parts
Šmalec, Petr ; Pavlík, Jan (referee) ; Kočiš, Petr (advisor)
The diploma thesis is focused on 3D printing of composites parts. Thesis deals with methods of additive manufacturing and describes principle of selected 3D printing technologies. In addition to additive technologies, the theoretical part presents an overview of composite materials and methods of composite production. Then there are four concepts that lead to 3D printing of continuous fiber reinforced composites components. The final concept is selected according to multi-criteria analysis and then designed. Designed extruder allows 3D printing of composite materials. The principle of the function consists of fiber impregnation by matrix inside the heat chamber and then deposition of composite on printing platform. The extruder also consist of fiber cutting mechanism. The extruder's ability is verified by the experiment.

The mechanical properties of fiber reinforcement laminates
Jílek, Jan ; Němec, Karel (referee) ; Válka, Libor (advisor)
This bachelor's thesis summarizes the current findings in the area of evaluation of mechanical properties of fibre reinforcement laminates. In the thesis an algorithm for acquiring material characteristics of laminate by calculation is introduced, the results are tested by tensile stress. Among the calculated and experimental values of material characteristics only a small difference was found. The effect of temperature on stiffening of laminate on mechanical properties is studied.

Joining of CFRP and metal parts
Dolinský, Jiří ; Urík, Tomáš (referee) ; Symonov, Volodymyr (advisor)
Tato práce popisuje základní principy spojování kompozitních materiálů a také spojování kompozitních materiálů s kovovými protikusy. Hlavním cílem této práce je navrhnout vhodný návrh spoje mezi kovovým závěsem a nosníkem křídla z uhlíkového kompozitu pro létající automobil AeroMobil 3.0. Pro výpočet napěťové analýzy byla použita speciální analytická metoda, která byla provedena za pomoci počítačových softwarů MATLAB a Excel. Konečný návrh spoje je vymodelován pomocí softwaru Autodesk Inventor. Předložené řešení není prakticky testovánu a tudíž by mělo být považováno pouze za přibližný návrh budoucího konstrukčního řešení.

Cutting forces when drilling fibre reinforced composites
Režný, Tomáš ; Sedlák, Josef (referee) ; Humár, Anton (advisor)
This master´s thesis is focused on fibre–filled composite materials, their distribution, labeling, usage, development and production. The aim of this work is complex processing of acquired technical knowledge, and evaluation of technological rehearsals of drilling composite materials which are reinforced by glas fiber and prepreg in terms of the impact of the machined material, wor-king conditions and the tool, and its wear to the feed force value and torque.
