Abstract

The Mode II critical strain energy release rate, GIIc, at room and elevated temperatures (333°C and 556°C) of Nicalon fiber/glass-ceramic 1723 matrix composite system was measured. The GIIC decreased slightly at 333°C in comparison to its value at room temperature. However, the GIIC increased three times at 556°C indicating a pronounced ductile behavior of glass-ceramic matrices at this elevated temperature.
