The outer layer and inner layer of the layered composites were made fromcon nitride and TiN (or SiC) -incorporated silicon nitride respectively. Results indicated that the mechanical and fracture properties oftes are functions of type and compositions of composites and the inner layer thickness. Ael was also used for calculating the compressive and tensile stress in the outer and inner layers forthe experimental results. By controlling the type and volume fraction of toughening phasesthickness , the flexural strength and toughness were substantially improved.
