Doctor blade material, which is composed of a number of layers that are connected to each other and include at least a frame layer. The frame layer, includes outer layers on both sides and is constructed of carbon fiber and/or mineral fiber, e.g. glass fiber, basalt fiber, et cetera. The outer layers include carbon fiber. The outer layer is a compact-multiaxial layer composed of a surface layer containing carbon fiber and of two or more support layers. The surface layer includes carbon fibers that are at a 90&#xb0; angle with respect to the longitudinal direction of the doctor blade, wherein the fibers in the first support layer following the surface layer are at an angle between (&#x2212;70&#xb0;)-(&#x2212;20&#xb0;) or (+20&#xb0;)-(+70&#xb0;) with respect to the fibers of the surface layer. The fibers in the second support layer following this are at an angle between (+20&#xb0;)-(+70&#xb0;) or (&#x2212;70&#xb0;)-(&#x2212;20&#xb0;) with respect to the fibers of the surface layer.
