Title: METHOD FOR REMOVING A METAL ELEMENT BONDED TO AN ELEMENT MADE OF COMPOSITE MATERIAL
Abstract:
The invention relates to a method for removing at least one portion of a metal part (3) bonded to a part made of composite material (2) of the carbon-epoxy type, comprising a step of degrading the bonding interface between the metal part (3) and the part made of composite material (2). The metal part (3) and the part made of composite material (2) are electrically connected to a DC voltage generator such that they are subject to an electrical potential difference in order to produce partial discharges in the bonding interface so as to degrade the latter.
