A method is provided for detaching a fiber layer from a multilayer fiber composite material. The fiber layer is one of a plurality of fiber layers of the fiber composite material. The plu- rality of fiber layers are embedded in a matrix material of the fiber composite material. The method comprises heating at least a portion of the matrix material to a temperature above a vaporization temperature of the matrix material or above a decomposition temperature of the matrix mate-rial to at least partially remove the matrix material from at least a portion of the fiber layer and mechanically detaching the at least partially matrix-free portion of the fiber layer from the remaining fiber composite material.
