Two-dimensional continuous carbon fiber toughened silicon carbide composite (2D C/SiC) z-pinned joint was prepared by a chemical vapor infiltration method. The microstructure features and the tensile behaviors were investigated, and the corresponding failure mechanism was analyzed. The results show that the joint is porous, non-uniform bonded with non-uniform clearance. The average joint shear strength reaches 157.77 MPa, which exceeds the 2D C/SiC in-plane shear strength. The main failure mechanisms involve debonding of the lap interface, bearing between the pin and the hole and fibers shear-off within the pin. Three typical damage morphologies appear around the hole, i.e., intact morphology, matrix crushing and pin-hole debonding.
