摘要: Abstract In this paper, 2D C/SiC z-pinned joint is prepared via chemical vapor infiltration. Effects of z-pin’s porosity on shear properties are investigated from the failure mode and damage mechanisms. The results show that average strength decreases asymptotically 249.9 MPa to 97.2 MPa as total z-pin increases 14.4% 27.3%. For each porosity, between tensile in-plane C/SiC, which rationalized by rigid body sliding model C/SiC. Because high leads large rotational deformation transverse fibers, a critical about 17.7% observed shear-controlled bending-controlled failure. A cohesive fracture developed build relation mechanical Very good accuracy obtained.
