Abstract
Composites of ceramic and metal exhibiting high fracture strength and toughness are formed from layers of the ceramic that have unequal concentrations and unequal porosity. The composites are made by a process that involves arranging layers of the ceramic in a predetermined pattern to provide a body that can be fully infiltrated by the metal.
