Abstract
Abstract Composites with Al 2 O 3 matrix and oriented SiC platelets were fabricated by tape casting and lamination. Suitable slips have been developed to obtain a homogeneous distribution of the components and a high degree of platelet orientation. The orientation has been improved by optimizing slip properties and by modifying the shape of doctor blades. The mechanical properties of laminates with different platelet sizes and contents have been determined. The highest fracture toughness (6·8 m ) is exhibited by samples with 15 vol.% SiC platelets (3–20 μm). These composites have a bending strength of 370 MPa.
