A flat vehicle body component made of a carbon fiber reinforced plastic has at least one interconnecting web that protrudes from the flat vehicle body component and that is made entirely of the matrix material epoxy resin. A mounting part at least partially envelops the interconnecting web in a force locking manner, so that the mounting part is clamped securely on the interconnecting web. The mounting part has at least one hole that can be used for fastening another component. An additional component may be fastened in the hole in a conventional manner, so that the carbon fiber reinforced plastic component does not need corresponding holes. The interconnecting web may be integrally molded on the vehicle body component during its manufacture so that practically no additional engineering effort is needed.
