摘要	Influences of different interlayer materials on mechanical properties of SiC matrix laminated ceramic composites were investigated. Gelcasting and hot-pressure sintering technologies were used to obtain the laminated SiC matrix composites with 5 different components of BN-Al2O3-SiC interlayers. The BN-Al2O3-SiC interlayer block materials and the SiC matrix material were also prepared by hot-pressure sintering. Mechanical properties of the laminated composites and block ceramics were tested. It was shown that the property of the interlayer material has very important influence on the mechanical properties and fracture behavior of laminated ceramic composites. It will make against the improvement of the mechanical properties of composites that the strength ratio of matrix to interlayer is too high or too low. When strength ratio reaches about 4.1, which is the optimal value, the crack deflection effect caused by interlayer is very notable in the fracture process of laminated composites, and the fracture toughness and fracture work of laminated composite are improved essentially, as well as the flexural strength of laminated composite maintains its high level.
