Summary

The forming of a ceramic composite in the configuration of a layered system with weak interfaces is one of the easiest ways to fabricate stronger and tougher ceramic components. In the present work, the fracture behavior of such ceramic systems was investigated. The effect of fracture energy difference between the strong and weak layers in the layered system was studied by the forming of laminates with various interlayer strengths. The effect of the strong and weak layer thickness ratio to the fracture behavior was also investigated. It is shown that both the layer fracture energy and the thickness ratio affect the mechanical behavior of the layered system.
