Potential and Perspectives for Oxide/Oxide Composites

M. Parlier, M.-H. Ritti & A. Jankowiak
The challenge for oxide/oxide composites is to provide an alternative to SiC/SiC composites with the aim of decreasing the cost of manufacture and improving the thermal stability in air at high temperature. Oxide/oxide composites consist of a porous alumina matrix reinforced by fibers of the same nature. Obtaining a controlled rate of porosity in the preparation helps to dissipate the energy associated with the propagation of cracks in the matrix during loading. It follows that...
