摘要

Laminated SiC_w/SiC ceramic composites were prepared by chemical vapor infiltration (CVI) and tape casting, and the advantages of this method were investigated. The results showed that this method can increase strength of the composites by reducing the damage of SiC whiskers and increasing their volume fraction, and increase toughness of the composites by controlling the interfacial bonding between whiskers and matrix and inter-laminar bonding between layers. The volume fraction of whiskers reached 40vol.%, and the flexural strength, tensile strength and fracture toughness were 315MPa, 158MPa and 8.02MPam^1/2, respectively. Interfacial and interlaminar crack deflection and bridging were observed.
