Transparent fibre reinforced ceramics
Lövy, Vít ; Drdlík, Daniel (referee) ; Chlup, Zdeněk (advisor)
This bachelor thesis summarizes possibilities of toughening of ceramic materials with various types of fibres and describes the basic principles for preparation of transparent fibre-reinforced composite materials. The role of fibre-matrix interface and the measurement methods enabling estimation of the interfacial strength and other characteristics are explained. The single fibre push-out test using a standard indentation technique was chosen for interfacial parameters determination of the composite consisting from a borosilicate matrix reinforced by SiC fibres in the practical part of this work.
Fracture behaviour of ceramic laminates with strong linked layers
Chlup, Zdeněk ; Slabáková, Lenka ; Drdlík, D. ; Hadraba, Hynek ; Dlouhý, Ivo
Multi-component ceramics materials having layered structure possess potential to be more convenient than monolithic ones. Depending on design a number of laminated structures can be distinguished. The most common division is by behaviour of layer interface i.e. with strong or weak interfaces. In this contribution the fracture behaviour of the laminates with strong interface allowing creation of residual stresses within layers will be described. Presence of residual stresses can enhance fracture properties. The alumina and zirconia were the components and electrophoretic deposition was used to prepare the laminate. Fracture behaviour was investigated using three point bending test of SEVNB specimens. Fracture surfaces were reconstructed and crack propagation changes were determined. Influence of residual stresses on fracture behaviour was found and described.
