Paper Title:
Design and Preparation of Laminated Composites
  Abstract

Active researches have been conducted to seek the application of ceramics as structural components. However, the lack of damage tolerance ability has been a critical problem. Laminated composites as one of the main way for improving the brittleness of ceramics are getting more and more attention from the biomimetic point of view. In the present paper, three laminated composites, SiC/TiC, Al2O3/Ni and ZrB2-SiC/ZrB2 with intentionally introduced surface compressive stress were presented. The finite element method (FEM) was used to simulation the stress distribution and to optimize the layered structure for the development of more reliable materials. Based on FEM analysis, the laminated structure was realized by aqueous tape casting and hot pressing. The dependence of mechanical properties (fracture strength and toughness) on the structural parameter (the composition of layers, the thickness ratio between layers, number of layers) was investigated. The calculated mechanical properties were in agreement with the tested ones to some extent.
