摘要： A porous substrate having a concave inside face and an outside face is disposed in an enclosure, and reactive gas is introduced into the enclosure to densify the substrate. At least a portion of the gas is divided into two non-zero fractions. The first fraction of the gas is fed to the inside face of the substrate. The second fraction of the gas is fed to only the outside face of the substrate. Alternatively, the first fraction of the gas is fed via a tooling extending into an inside volume defined by the concave inside face of the substrate.

摘要： The substrate (10) is placed in an enclosure (12) and is heated so as to establish therein a temperature gradient such that the substrate has a higher temperature in portions that are remote from its exposed surfaces than at its exposed surfaces. A reaction gas constituting a precursor for the material to be infiltrated is admitted into the enclosure, with formation of the material being enhanced in those portions of the substrate that are at higher temperature. At the beginning of the infiltration process, and at least during the major portion thereof, substrate heating is controlled in such a manner as to maintain the temperature of its exposed surfaces at a value that is no greater than the minimum temperature for the reaction gas to deposit the material that is to be infiltrated, while portions of the substrate that are remote from its exposed surfaces are at a temperature that is greater than the minimum temperature for deposition.

摘要： Between the start and the end of the chemical vapor infiltration process, filtration conditions are modified by causing at least one of the following infiltration parameters to vary: retention time of the gas, pressure, temperature, concentration of precursor in the gas, and concentration of dopant, if any, in the gas; thereby adapting infiltration conditions to changes in the porometry of the substrate in order to control the microstructure of the material deposited within the substrate, in particular in order to conserve a microstructure that is constant.

摘要： A method for densification of porous by CVI in which substrates are loaded into a loading zone of an oven and heated to a temperature at which a desired matrix material is formed from a precursor gas(es). A reative gas containing the precursor gas(es) is admitted into the end of the oven and heated upstream from the loading zone of the substrates. The reactive gas is also preheated prior to entering the oven so that, upon entering the oven, it is brought to an intermediate temperature between ambient temperature and the temperature to which the substrates are heated. In this manner, a very small temperature gradient is obtained throughout the loading zone.

摘要： A fiber preform is obtained by conforming panels of fiber texture on a former having a surface that reproduces the shape desired for a surface of the nozzle or the nozzle divergent section that is to be made. The panels are bonded together via their mutually contacting edges. A consolidated fiber reinforcement is formed by shaping the fiber preform impregnated with a consolidation composition including a resin. The shaping of the fiber preform is performed between the former and a jacket applied against the impregnated fiber preform so as the consolidated fiber reinforcement has a fiber volume percentage of at least 35%, and a thickness of less than 5 mm over at least a major fraction of its axial dimension. The densification of the fiber reinforcement is continued by chemical vapor infiltration after pyrolyzing the resin so that once densified, a part is obtained that has practically the shape and the wall thickness of the nozzle or the nozzle divergent section that is to be made.
