Study of electric properties of composite
Bariš, Marián ; Havlíček, Svatopluk (referee) ; Polsterová, Helena (advisor)
The theme of this Bachelor's thesis is a problematics of composite materials. On a given samples of polyamide with a various weight filling of a milled mica were measured resistivity, permittivity and loss factor on a consequence of a temperature and filling. The chosen type was a filling with a milled mica in range from 0 to 40 of a weight percentage, temperatures were in range from 20 °C to 90 °C.

Dielectric Properties of Thermoplastic Materials with Ground Mica
Fiala, Ivo ; Havlíček, Svatopluk (referee) ; Polsterová, Helena (advisor)
The subject of this thesis are composite materials, measuring of their dielectric qualities, particularly of the polyamide and the polyamide filled with various weight percentage of the ground mica. The essential intent of the thesis is to determine the measuring methodology and respective measurement of the basic dielectrical quantities of materials, as are loss factor and the complex permitivity components. The measuring should be done for various temperature and humidity combinations. The thesic contains the physical explanation of measured dependences.

Study of electric properties of composite
Macháček, Miroslav ; Havlíček, Svatopluk (referee) ; Polsterová, Helena (advisor)
This work deals with issues of composite materials. The general aim is to observe how the amout of filling infuence dielectric spectrum which is measured on prepared samples. For this purpose had been created variety of a samples with different percentage of filling with mica. Measured values had been compared with theoretically values, determinated using mixture formulas.

Influence of the Temperature on the Dielectric properties epoxy with ground mica
Ráček, Tomáš ; Havlíček, Svatopluk (referee) ; Polsterová, Helena (advisor)
The paper is focused on theoretical analysis of the basic characteristics of dielectrics, especially on the examination of these qualities at samples of epoxy sealing compound filled with powder mica, and their dependance on the temperature and the content of filling in the material. The measured quantities are inner resistivity, relative permitivity, and loss factor. The paper also deals with the sensitivity of the material to humidity, and through the influence of humidity to the other measured quantities.
