Abstract: Laminated ceramic composites which have a unique structure, have been used in tailoring the microstrucure and mechanical properties
of structural ceramics, and it is shown that both strength and toughness can be improved. In this paper, the different mechanisms that can be
used to reinforce laminated ceramic composites were reviewed in two parts at macroscopic scale. Furthermore, optimum design of such composites
was briefly pointed out, and as an example, the fracture toughness was optimized by discussing the effects of changes in specimen variables,
including lamina strength, interface bonding strength, as well as interface and lamina thickness in details.

Key words: laminate composite, ceramic fracture, toughening, strengthening, optimum design
