1. A patch strip comprising a plurality of quick-repair patches for renovating local and structurally mechanically irrelevant damage to a component or an aircraft component, comprising a covering layer and lightning-strike surface protection located therebeneath, wherein each of the quick-repair patches has a layer structure and the layer structure comprises:
a plastic film layer, which is configured to be materially bonded to the covering layer in an arrangement in which the plastic film layer faces away from the damage when the quick-repair patch is fastened to the component;
an electrically conductive lightning-protection layer which is suitable for a lightning-protection function or an electromagnetic-interference-protection function and is bonded to the plastic film layer, wherein the lightning-protection layer is configured to make electrically conductive contact with the lightning-strike surface protection when the quick-repair patch is fastened to the component; and
a fastening layer, which is suitable for fastening the quick-repair patch to the component by a material bond;
wherein the lightning-protection layer defines a surface area that is smaller than a surface area of the plastic film layer such that the plastic film layer defines a peripheral region which is between a contour of the plastic film layer and the lightning-protection layer;
wherein the fastening layer is arranged only on the peripheral region of the plastic film layer on a same side as the electrically conductive lightning-protection layer; and
wherein the quick-repair patches are individually separably connected to one another at an edge of the peripheral region.
