9. A rotor blade component for a rotor blade of a wind energy installation, the rotor blade component comprising:
at least one first layer system comprising a first layer of a first material and a second layer of a second material;
wherein the second layer is at least partially applied to the first layer along a longitudinal direction;
wherein the second material has a lower modulus of elasticity in the longitudinal direction than the first material;
wherein each of the first and second layers of the layer system is beveled at least at one end such that the beveled end of the first layer and the beveled end of the second layer together form a continuous beveled end surface, and such that the second layer projects beyond the first layer at the at least one end of the layer system;
wherein the second layer is incorporated only in a region of the at least one end of the first layer in which the layer system is beveled; and
at least one second layer system connected to the at least one first layer system to form the rotor blade component.
