Abstract
A compressor blade of a gas turbine includes an airfoil made of a fiber-reinforced plastic and a leading-edge element connected to said airfoil. The leading-edge element includes two partial elements, which are fabricated as separate elements and connected to one another, with the leading-edge element being connected to the airfoil essentially using the clamping effect of the two partial elements.
