This process unites two fibrous composite components of differing construction, over an adjoining region. The first of these regions (5) is constructed independently, from a blank preform (9). This is enclosed by a vacuum film, with a section of transition film (8) located in the adjoining region. The enclosure is evacuated and infiltrated with resin (22). The other adjoining region (6) is constructed from a prepreg blank (2). The adjoining regions (5, 6) are then brought together and joined, sealing off the other adjoining region (6). During common thermal treatment, the other adjoining region is evacuated to remove excess air. Before common thermal treatment, the resin of one bordering region (5) is prehardened. Parts of the transition film (8) project initially beyond the contact zone of the adjacent regions. After final thermal treatment, this excess is removed. |
