  • Patent number: 9259896
    Abstract: 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° 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 (?70°)-(?20°) or (+20°)-(+70°) with respect to the fibers of the surface layer. The fibers in the second support layer following this are at an angle between (+20°)-(+70°) or (?70°)-(?20°) with respect to the fibers of the surface layer.
