Determining the fracture resistance of fibre-reinforced glass matrix composites by means of the chevron-notch flexural technique.

Original language description

Results on fracture toughness determination on SiC fibre reinforced borosilicate glass matrix composites after thermal cycling and thermal shock are presented. The thermal shock tests involved quenching the samples from high temperatures (600-650 C) in awater bath at room temperature. For the thermal cycling tests the samples were alternated between a furnace at high temperature (700 C) and room temperature for up to 1000 cycles in air. Fracture toughness and work of fracture were measured using the chevron notched specimen technique. Supported by fracture surface observations, the results were used to assess the microstructural damage in the material after thermal loading. To detect the onset of unstable microcracking during the chevron-notch experiments, acoustic emission technique was used. The present results were shown to be in agreement with data of previous studies in which other techniques (Young's modulus and internal friction determination, fibre push-out test) were used to
