  • Method, device and diagnostic program for densification faults of a CMC part

    Émis le FR FR3097328A1

    The invention relates to a method for diagnosing densification defects of a composite part with a ceramic matrix, in which (E1) is acquired by a tomographic imaging device a tomographic image (I) of the part. We determine (E2) for an area (Z) of the image, a histogram (H) of the gray levels (NG), we calculate (E3) a distribution law (LN) of the frequencies (f) of the levels (NG ) of gray, approaching the histogram (H), we calculate (E4) the theoretical frequency (fth) of the law (LN)…

  • Method for manufacturing a part made from CMC

    Émis le OO WO2020025878A1

    A method for manufacturing a part made from composite material having a matrix that is at least mainly ceramic comprises: - producing a fibrous structure (100) by three-dimensional or multilayer weaving; - shaping the fibrous structure in order to form a fibrous preform core (200); - depositing an interphase on the fibres of the preform core; - consolidating the preform core (200) by partial densification of the core, comprising the formation of a matrix phase by gas-phase or liquid-phase…
