Laminated composites can be designed to increase the toughness of inherently brittle ceramic bodies. The formation of laminated composites by a novel processing route is discussed. An extrusion die was designed to facilitate the co-extrusion of two materials of similar rheological properties into multilayer composites. Alumina/zirconia, zirconia-toughened-alumina (ZTA)/alumina and ZTA/zirconia composites were formed by co-extrusion. The effects of paste rheology and component densification rates on the processing and properties of the composites is discussed, with particular reference to defect formation.
