Doctor blade material, which is composed of a number of layers (1, 2) that are connected to each other, which layers comprise at least a frame layer (1) and, with respect to the frame layer, outer layers (2) on both sides of it, which frame layer (1) is carbon fiber and/or mineral fiber, e.g. glass fiber, basalt fiber, et cetera, and which outer layers (2) comprise carbon fiber. The invention is implemented such that the outer layer (2) is a compact-multiaxial layer, which is composed of a surface layer (2') containing carbon fiber and of two or more support layers (2", 2"'), in which surface layer the carbon fibers are at a 90° angle with respect to the longitudinal direction of the doctor blade, in which case the fibers in the first support layer (2") following the surface layer (2') are at an angle with respect to the fibers of the surface layer, which angle is between (-70°) - (- 20°) or (+20°) - (+70°), and in that the fibers in the second support layer (2"') following this are at an angle with respect to the fibers of the surface layer (2'), which angle is between (+20°) - (+70°) or (-70°) - (-20°). |
