VERFAHREN ZUR HERSTELLUNG EINER MIT EINEM CMC-FLUSSMISCHER AUSGESTATTETEN STRUKTUR FÜR EINEN TURBINEN-LUFTMOTOR |
摘要 |
The method involves forming a fibrous preform (100) in refractory fibers having a shape corresponding to that of a lobes structure to be fabricated from fibrous constitutive elements. The elements are assembled to each other and are shaped using a shaping tool corresponding to that of the structure to be fabricated for obtaining the preform that is assembled with an annular preform part (111) corresponding to an annular part e.g. ring sector, and a multi-lobed preform part (112) corresponding to a multi-lobed skirt sector. The shaped preform is densified and assembled by a ceramic matrix. |
