<p>Provided is a method and apparatus for monitoring a mixture of at least two components. Also provided is a rotor blade of a wind power installation, a gondola casing of a wind power installation and a wind power installation itself. To provide a method in which the composition of the mixture can be easily monitored without damaging the workpiece produced therefrom, a dye is added to each component, wherein added to each component is its own color which is different from that of the other components, and the mixture of those components is monitored colorimetrically. A gondola casing and/or a rotor blade is manufactured by using such a method to determine amounts of components to include in a material of which the gondola casing or rotor blade is to be made.</p> |
