Two different types of SiC f /SiC composites were successfully joined using a zinc borate glass as a joining agent. The characterization of the joined specimens included XRD, DSC, DTA, SEM‐EDS, macroporosimetry, and shear testing measurements. For both composites, the interfaces were continuous and crack‐free, and a reaction occurred between the liquid glass and the composite's surface. The large porosity of the chemical vapor deposited (CVI) composite allowed the glass to infiltrate the sandwich structure, the driving force being gaseous product pressurization and capillary surface forces.
