PROCEDE DE COLLAGE DE PIECES INTERMEDIAIRES DE FABRICATION DITES PIF SUR UNE AUBE EN MATERIAU COMPOSITE DE TURBOMACHINE |
摘要 |
A method for bonding additional parts to a composite-material turbomachine part in a thermostatic oven includes a step of placing this composite-material turbomachine part equipped with the additional parts on a rigid support that cannot deform at the operating temperature and pressure and that is configured to espouse the desired final shape of the composite-material turbomachine part. The composite-material turbomachine part equipped with these additional parts is covered with a vacuum bag. The edges of this vacuum bag are sealed with respect to the non-deformable rigid support. A vacuum of determined pressure is applied to the vacuum bag. The determined operating pressure is applied to the vacuum bag in order to hold the composite-material turbomachine part equipped with these additional parts firmly against the non-deformable rigid support, the whole entity thus formed is heated to the operating temperature in the thermostatic oven for a determined time. |
