摘要： A composite material part is made by forming a fiber preform (20), forming holes (22) extending within the preform from at least one face thereof, and densifying the preform with a matrix formed at least in part by a chemical vapor infiltration (CVI) type process. The holes (22) are formed by removing material from the preform with fibers being ruptured, for example by machining using a jet of water under pressure, the arrangement of the fibers in the preform with the holes being substantially unchanged compared with the initial arrangement before the holes were formed. This enables the densification gradient to be greatly reduced, and it is possible in a single densification cycle to obtain a density that, in the prior art, required a plurality of cycles separated by intermediate scalping.

摘要： To densify thin porous substrates (1) by chemical vapor infiltration, the invention proposes using loading tooling (10) comprising a tubular duct (10) disposed between first and second plates (12, 13) and around which the thin substrates for densification are disposed radially. The tooling as loaded in this way is then placed inside a reaction chamber (20) in an infiltration oven having a reactive gas admission inlet (21) connected to the tubular duct (11) to enable a reactive gas to be admitted into the duct which distributes the gas along the main faces on the substrates (1) in a flow direction that is essentially radial. The reactive gas can also flow in the opposite direction, i.e. it can be admitted into the tooling (10) from its outer envelope (16) and can be removed via the duct (11).

摘要： A composite material protected by oxidation at intermediate temperatures exceeding 850.degree. C. comprises fiber reinforcement densified by a matrix which includes at least one self-healing phase including a glass-precursor component such as B.sub.4 C or an Si--B--C system, together with excess free carbon (C) at a mass percentage lying in the range 10% to 35%. The, or each, self-healing phase can be interposed between two ceramic matrix phases, e.g. of SiC. While the material is exposed to an oxidizing medium, oxidation of the free carbon promotes oxidation of the precursor and transformation thereof into a glass capable of plugging the cracks in the matrix by self-healing.

摘要： The interphase is formed by nanometric scale sequencing of a plurality of different constituents including at least a first constituent that intrinsically presents a lamellar microtexture, and at least a second constituent that is suitable for protecting the first against oxidation. A plurality of elementary layers of a first constituent of lamellar microtexture, e.g. selected from pryolytic carbon, boron nitride, and BC.sub.3 are formed in alternation with one or more elementary layers of a second constituent having a function of providing protection against oxidation and selected, for example, from SiC, Si.sub.3 N.sub.4, SiB.sub.4, SiB.sub.6, and a codeposit of the elements Si, B, and C. The elementary layers of the interphase are preferably less than 10 nanometers thick and they are formed by chemical vapor infiltration or deposition in pulsed form.
