A method for fabricating a repair laminate for a composite part having an exposed surface includes applying a release film to the exposed surface and forming an uncured ply stack assembly on the release film. The uncured ply stack assembly is formed by forming and compacting a series of uncured ply stacks. The release film and ply stack assembly is then removed from the exposed surface. A bonding material is then applied to the exposed surface, and the uncured ply stack assembly is applied to the bonding material. The ply stack assembly and bonding material are then cured.

Un procédé de fabrication d'un stratifié de réparation pour une pièce composite présentant une surface exposée comprend l'application d'un film amovible sur la surface exposée et la formation d'un empilement de couches non traitées sur le film amovible. L'empilement de couches non traitées est formé en formant et en compactant une série de couches non traitées empilées. Le film amovible et l'empilement de couches sont ensuite retirés de la surface exposée. Un matériau de liaison est ensuite appliqué sur la surface exposée, et l'empilement de couches non traitées est appliqué sur le matériau de liaison. L'empilement de couches non traitées et le matériau de liaison sont ensuite traités.
