This research is part of the PERSEUS project, a space program concerning hybrid propulsion and supported by CNES. The main goal of this study is to characterize a silicon carbide based micro-concrete with a maximum aggregates size of 800 microns, in a hybrid propulsion environment. The nozzle throat has to resist to a highly oxidizing polyethylene/N2O hybrid environment, under temperatures ranging from room temperature up to 2800K. The study is divided in three main parts: the first one deals with the thermo-mechanical characterization of the materials up to 1500K, the second one with an investigation on the oxidation behaviour in a standard atmosphere, under a solar flux up to 15 MW/m2, the last part deals with the conception, the realizat...
