Claim 0:
1. A method for applying a material to a fiber composite component within an application region of the fiber composite component, wherein the fiber composite component is a fiber composite material comprising a fiber material and a first matrix material, comprising:
providing a woven monofilament fabric comprising a woven configuration of threads embedded in a second matrix material, wherein a plurality of the threads or all of the threads are each composed of an individual filament,
wherein the provided woven monofilament fabric has a total base area and comprises warp monofilament threads and weft monofilament threads in a woven configuration defining meshes, each mesh having an open area, wherein a sum of all the meshes' respective open areas is at least 30% of the total base area of the woven monofilament fabric;

arranging the woven monofilament fabric on an application region of a fiber preform which is formed of the fiber material of the fiber composite material;
forming a materially bonded connection between the woven monofilament fabric and the fiber preform, comprising curing the first matrix material in which the fiber material of the fiber preform is embedded, and the second matrix material in which the threads of the woven monofilament fabric are embedded, in a common process step and,
after forming the materially bonded connection between the fiber preform and the woven monofilament fabric,
forming a cohesively fractured surface on the application region of the fiber preform, comprising pulling off the woven monofilament fabric from the fiber preform in a manner cohesively fracturing the materially bonded connection, and
applying material on the cohesively fractured surface in the application region,
wherein the woven monofilament fabric is provided in such a way that, after the woven monofilament fabric has been pulled off, a sum of all cohesively fractured regions within the application region corresponds to at least 30% of a total area of the application region.
