Film adhesive for the adhesive joining of at least two joining partners (11, 12), which contains an adhesive for an adhesive connection of the joining partners (11, 12) and a textile, flat carrier material, the adhesive being applied to the textile, flat carrier material in a film-like manner, characterized in in that the textile, flat carrier material has at least one first section which adjoins at least one second section of the carrier material, the carrier material of the first section being modified with respect to the carrier material of the second section in such a way that, after the adhesive has cured, the adhesive bond in the region of the first section has a mechanical property with respect to the fracture strain or fracture toughness which is different from the mechanical property of the adhesive bond in the region of the second section, whereby the textile, flat carrier material being completely enclosed and impregnated by the adhesive and being open-pored, so that the adhesive bond is realized exclusively by the adhesive and the carrier material thus does not become a joining partner, - wherein the textile, flat carrier material is materially modified in one of the first sections in such a way that the material of the carrier material in these regions is a material which, when the adhesive cures, undergoes a chemical reaction with the this in order to bring about the desired mechanical property in the first sections, - wherein the textile, flat carrier material is chemically modified in one of the first sections in such a way that additional substances, particles and/or fillers are added to the carrier material in this region or regions, which enter into a chemical reaction with the adhesive when the this cures, in order to bring about the desired mechanical property in the first sections, and/or - wherein the textile, flat carrier material is geometrically modified in one of the first sections in such a way that the material of the carrier material in these regions is a material which, after the adhesive has cured, produces a higher or lower thickness of the adhesive bond than in the regions of the second sections. - wherein the textile, flat carrier material is materially modified in one of the first sections in such a way that the material of the carrier material in these regions is a material which, when the adhesive cures, undergoes a chemical reaction with the this in order to bring about the desired mechanical property in the first sections, - wherein the textile, flat carrier material is chemically modified in one of the first sections in such a way that additional substances, particles and/or fillers are added to the carrier material in this region or regions, which enter into a chemical reaction with the adhesive when the this cures, in order to bring about the desired mechanical property in the first sections, and/or - wherein the textile, flat carrier material is geometrically modified in one of the first sections in such a way that the material of the carrier material in these regions is a material which, after the adhesive has cured, produces a higher or lower thickness of the adhesive bond than in the regions of the second sections.
