The method comprises joining a metal part (2) and a part made of polymeric material (4) to form a junction surface (6), and introducing a metal connecting element (12) into the polymeric material part such that an inner end of the connecting element is in contact with the metal part and welded to the metal part in the junction surface to ensure the fixation of the polymeric material part to the metal part. An external end (16) of the connecting element levels an external part of the polymeric material part according to the junction surface. The method comprises joining a metal part (2) and a part made of polymeric material (4) to form a junction surface (6), and introducing a metal connecting element (12) into the polymeric material part such that an inner end of the connecting element is in contact with the metal part and welded to the metal part in the junction surface to ensure the fixation of the polymeric material part to the metal part. An external end (16) of the connecting element levels an external part of the polymeric material part according to the junction surface. The welding of the connecting element to the metal part is realized by providing current. The metal connecting element is formed by a metal staple that includes two longitudinal branches, where the branches are introduced into the polymeric material part such that a free end the branches is in contact with the metal part in junction surface. The longitudinal branches are connected with each other by a transverse branch. The staple is introduced into the polymeric material part such that the transverse branch extends along an external part of the polymeric material part. The metal part and the polymeric material part include edge extending to a principal direction of the parts. The connecting element is introduced into the polymeric material part through an edge of the polymeric material part, where the length of the connecting element is approximately equal to the thickness of the edge of the polymeric material part. The metal part is welded with the polymeric material part in several points. The transverse branch of one of the staples extends according to a direction different from the transverse branch from another staple. The polymeric material part is formed by a thermoplastic or thermo hardening material reinforced by fibers. An independent claim is included for a hybrid part for a car. |
