• The effect of structure and chemistry of interphase on the fracture behaviour of the SiC fibre/pyrex composites has been examined using TEM and PEELS. For all Nicalon/pyrex samples investigated, interfacial layers of 〜30-35nm thickness were observed, regardless of variations in the interfacial stress and difference in fracture mode. The sample of Tyranno fibre-reinforced pyrex which fractured in a brittle manner, and showed extensive diffusion of matrix elements into the fibres had a much thicker interfacial layer of 〜100nm thickness. SAD pattern and PEELS data confirmed that the interfacial layer in Tyranno/pyrex was carbon-rich. This indicates that the presence of a carbon-rich interfacial layer does not necessarily lead to damage-tolerant composites.
