Original abstract

The behaviour of a propagating crack when an interface is present is a key feature in composite materials. The aim of the work is to indicate a possible way for the determination of interface characteristics suitable as inputs for numerical calculations. The introduced testing methodology was tested on spinel composite ceramics reinforced by unidirectional SiC fibre. The adopted method for fracture toughness determination is using a chevron notch technique. Additionally, fractographical techniques were used when interpreting the measured values.

Czech abstract

Chování šířící se trhliny v blízkosti rozhraní je klíčové pro charakterizaci kompozitních materiálů. Cílem práce bylo najít možnou cestu k určení charakteristik rozhraní, které budou vhodné jako vstupní data pro numerické výpočty. Vyvinutá zkušební technika byla testována na kompozitu tvořeném matricí spinelu vyztuženou jednosměrnými vlákny SiC. Metoda využívá techniky chevronových vzorků. Pro interpretaci výsledků byla využita fraktografická pozorování.
