Abstract: A method for producing a fibrous preform includes placing a fibrous mat onto a depositing surface, the depositing surface being formed by a web face of a mold core, a first support surface of a first support installation and a second support surface of a second support installation. The fibrous mat is covered by a film and is pressed in a planar manner onto the depositing surface by generating a vacuum. Bringing to bear the fibrous mat on lateral faces of the mold core that extend transversely to the web face is subsequently performed by moving the support installations and the mold core relative to one another in such a manner that a level differential between the web face of the mold core and the support surfaces of the support installations is enlarged. A device for producing a fibrous preform is furthermore described.

Abstract: A device for producing a curved fiber preform from a bi- or multidirectional fiber semi-finished product, in particular for an aircraft or spacecraft fuselage component has first lamellae and second lamellae formed to be couplable to one another criss-cross such that they are positioned on a shared plane and thus form a grid. The lamellae at least in part are formed resiliently bendable about an axis intersecting the shared plane such that a local orientation of the lamellae in the grid changes. An adhesion device or structure is formed for temporarily adhering the fiber semi-finished product and is configured such that the local fiber orientation of the fiber semi-finished product also changes accordingly when the lamellae bend.
