Preparation of ceramic-metal composites for ballistic protection
 Hladík, Jakub ; Roleček, Jakub (oponent) ; Salamon, David (vedoucí práce)
Aim of this bachelor thesis is fabrication of ceramic-metal composite for ballistic protection, the main focus is on the materials interface. Properties of used ceramic and metal materials are described as well as applicable mechanical tests. Alumina / aluminum composite was prepared experimentally by gravity casting/sintering of aluminium among the alumina hexagons. Various temperature conditions were tested to achieve the optimal casting conditions at the lowest possible temperature. Prepared composite was tested by a ballistic impact according to NIJ Standard-0108.01 and NATO Standard STANAG 2280. Properties of the aluminium/alumina interface were verified by the fracture analysis of damaged samples and by a special version of four-point beam bending test. Also, a brief examination of aluminium microstructure was made.
