Abstract:
A rotor blade for a wind energy installation includes a blade root, a blade tip, and at least one rotor blade shell extending in a longitudinal direction from the blade root to the blade tip, and having an inner shell region and an outer shell region. The inner shell region includes a first fiber composite with at least two first fiber layers, and the outer shell region includes a second fiber composite with at least two second fiber layers. The first and second fiber layers extend substantially in the longitudinal direction. At least a first fiber layer of the first fiber composite terminates in the region of at least one end position in the longitudinal direction, whereas the remaining first fiber layers extend beyond the end position. At least a second fiber layer of the second fiber composite terminates in the region of the end position in the longitudinal direction, whereas the remaining second fiber layers extend beyond the end position.
