Ceramic matrix composites have been widely used in aero-engines due to their excellent mechanical properties and low density. But the composite riveted joint usually suffers more serious stress distribution. The objective of this study is to provide some helpful information on the mechanical properties of SiCf/SiC composite riveted joint. Compressive load was applied to test each SiCf/SiC riveted joint at room temperature. Results showed that the SiCf/SiC riveted joints possessed high shear stiffness and shear strength. Local damage would appear in the riveted joint and result in a sudden decrease of the compressive load when the applied load approximated the limit load. Meanwhile, the high-temperature adhesive implemented between the SiCf/SiC plates could provide a certain joint strength. The SiCf/SiC riveted joints exhibited brittle shear fracture modes, and the bonding strength of the composite interface between the fiber and the matrix was suitable for the present study.
