Influence of Interlayer on Mechanical Properties of Laminated Ceramic Matrix Composites

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-Al_2O_3- SiC interlayers. The BN-Al_2O_3-SiC interlayer block materials and the SiC matrix material were also Prepared by hot-prssure sintering. Mechanical properties other laminated composites and block Ceramics were tested. It was shown that the property o the interlayer material has very important Influence on the mechanical properties and fracture behavior of laminated ceramic composites.
