Abstract: The paper postulated various possible toughening mechanisms existing in ceramic composite, while discussed the factors that in fluenced the toughening effects of these mechanisins. It seemed that these mechanisms did not exist independently and there were interdependent and interacting relations between them; the same factor( for example grain size, Yong' s Modulus,etc.) could also give quite different influence to different toughening mechanism, sometimes even the opposite one. In order to get ceramics with desirable properties. material scientist should reinforce some toughening mechanisms selectively, according to the compositional characteristic of the material

Keywords: ceramic composite, toughening mechanism
