Claim Text:
1. A doctor blade material, which is composed of a plurality of layers that are connected to each other, which layers comprise at least one frame layer and outer layers disposed on both sides of the at least one frame layer, said at least one frame layer is carbon fibers and/or mineral fibers selected from the group consisting of glass fibers and basalt fibers and said outer layers comprise carbon fibers, wherein the outer layers are compact-multiaxial layers, which are composed of at least one surface layer containing carbon fibers and of two or more support layers, wherein, in the surface layer, the carbon fibers are at a 90° angle with respect to a longitudinal direction of the doctor blade; in the first support layer following the surface layer, the fibers are at an angle with respect to the fibers of the surface layer of between (−70°)-(−20°) or (+20°)-(+70°), and the fibers in the second support layer adjacent to the first support layers are at an angle with respect to the fibers of the surface layer of between (+20°)-(+70°) or (−70°)-(−20°).
