Abstract
The invention relates to a method of separating at least one portion of a metallic part () glued to a composite material part () of the carbon-epoxy type, comprising a step to degrade the glued interface between the metallic part () and the composite material part (). The metallic part () and the composite material part () are electrically connected to a dc electrical voltage generator so that an electrical potential difference can be applied to them to generate partial discharges in the glued interface to degrade the interface.
