ABSTRACT:
Novel ceramic matrix composition comprising toughened ceramic layers interlaminated with fiber-reinforced ceramic layers and offering improved off-axis and axial properties, are described. The fiber-reinforced layers comprise inorganic reinforcing fibers disposed in a ceramic matrix material, with the reinforcing fibers being oriented along axes parallel with the planes of the layers, while the toughened ceramic layers comprise inorganic whiskers or chopped fibers randomly oriented in the layers.
