Summary:The properties of laminated ceramic systems, especially those with low-strength bonds, are discussed. It is shown that residual stresses, which depend on the physical and mechanical characteristics (such as strength, thermal expansion coefficient, thickness, intensity of interfacial interaction) and structure of the main layers and interlayers, affect the fracture behavior of composites. Laminated materials with low sensitivity to defects and strength as high as that of the main layer were produced using a number of oxygen-free refractory compounds.
