Abstract:Ultra-high temperature ceramic matrix composites based on a ZrB2/SiC matrix have been investigated for the fabrication of reusable nozzles for propulsion. Three De Laval nozzle prototypes, obtained by sintering with either hot pressing or spark plasma sintering, were tested 2-3 times in a hybrid rocket motor for proving reusability. Sections were extracted after oxidation tests to study the
