Production of composite materials using vacuum infusion
Ciran, Adam ; Gregor, Lukáš (referee) ; Zouhar, Jan (advisor)
The theoretical part of the bachelor thesis deals with the definition of composite material, then the division of the most used fabric reinforcements and matrices, with a focus on reinforcements made of glass and carbon fiber and flax fiber. It then discusses vacuum infusion techniques, their description and applications. In the practical part, emphasis is placed on the fabrication of specimens using vacuum infusion technology of carbon fiber, glass fiber and flax using an epoxy matrix. The last part is the evaluation of the fabricated samples.
The combined effect of glass fibers and titanium oxide as the negative electrode additive on the properties of the lead accumulator
Gerlich, Jakub ; Vaculík, Sebastian (referee) ; Bača, Petr (advisor)
This thesis deals with the problematic of lead acid batteries for HEVs. It starts with classification of electrochemical cells then proceeds to focus on lead acid batteries, mainly because they are the most used source of electrical power in automotive industry. The practical part of the work describes the process of manufacturing the electrode system used in the later parts. The experimental part is focused on the behaviour of the cells under conditions that appear in hybrid electric vehicles. The effect of aditives in active matter of the negative electrode on the parameters of the cells is observed, such as voltage, capacity and operating life
