Abstract
A method of manufacturing a part out of impervious thermostructural composite material, the method comprising forming a porous substrate from at least one fiber reinforcement made of refractory fibers, and densifying the reinforcement by a first phase of carbon and by a second phase of silicon carbide. The method then continues by impregnating the porous substrate with a composition based on molten silicon so as to fill in the pores of the substrate.
