Abstract
A film is applied as an intermediate between two parts to be joined in a liquid composite molding process, whereby at least one of the two parts comprises a fiber structure. The film has two main surfaces, one of which is adapted to contact one of the two parts to be joined, the other main surface being adapted to contact the other one of the two part to be joined. The film includes a plurality of cavities. An orthographic projection of the cavities onto one of the two main surfaces as a projection plane, occupies at least 5% of this main surface.

A film for use as an intermediate between two parts to be joined in a liquid composite molding process, at least one of the two parts comprising a fiber structure, the film having two main surfaces one of which is adapted to contact one of the two parts to be joined, the other main surface being adapted to contact the other one of the two part to be joined, wherein the film comprises a plurality of cavities in a volume between two surface layers one of which extends from inwardly from one of the two main surfaces, the other surface layer extending inwardly from the other one of the two main surfaces, whereby an orthographic projection of the cavities onto one of the two main surfaces as a projection plane, occupies at least 5% of this main surface.
