Method of repairing damage to a thermoplastic composite element

A method of repairing damage to a thermoplastic composite element, comprising milling a socket at a site of damage to the thermoplastic composite element, then in said socket, forming a patch from a thermosetting material containing a reinforcing phase of fabric layers and a matrix of thermosetting resin, said patch having a shape and a size corresponding to a socket geometry, curing the patch and finally gluing the cured patch into the socket by means of an adhesive, wherein in the step of forming the patch in the socket, the following are placed sequentially:

• a separating layer in a form of a film or a separating agent;
• sections of fabric layers constituting the reinforcing phase of fabric layers of the thermosetting material, impregnated with a matrix of thermosetting resin, whereby a number of the sections of fabric layers, their total thickness as well as a shape and size of individual sections corresponds to the geometry of the socket;
• and
• then covering the prepared patch successively with:
• a perforated separating foil, an absorbing fabric, a separating foil, a heating blanket, a breathable fabric and a vacuum foil, and an entire repair package thus formed is sealed to a surface of the thermoplastic composite element being repaired by a sealing tape.
