(EN) METHOD FOR MAKING A STRUCTURAL PART FOR AN AUTOMOBILE AND PART THUS OBTAINED
(FR) PROCEDE DE FABRICATION D'UNE PIECE STRUCTURELLE DE VEHICULE AUTOMOBILE ET UNE TELLE PIECE
Abrégé
(EN)
The invention relates to a method for making an over-moulded part (10) that defines a structural part for an automobile, comprising: a moulding step during which at least one member (12) of the part (10) is moulded from a first material containing a heat-curable material, using a mould (24) shaped so that at least a portion of the member forms a material web (30); an over-moulding step during which a second material containing a heat-curable material is over-moulded on at least one of the material webs (34) of the member (12) so that the material web (34) is torn under the pressure (42) of the second material, a passage (35) for the second material being then formed through the member. The invention also relates to a structural part for an automobile.
(FR)
L'invention a pour objet un procédé de fabrication d'une pièce surmoulée (10) formant une pièce structurelle de véhicule automobile, comprenant: une étape de moulage lors de laquelle on moule au moins un élément (12) de la pièce (10) en un premier matériau à base de matière thermodurcissable, à l'aide d'un moule (24) conformé pour qu'au moins une portion de l'élément forme un voile de matière (30), une étape de surmoulage lors de laquelle on surmoule un deuxième matériau à base de matière thermoplastique sur au moins l'un des voiles de matière (34) de l'élément (12), de sorte que le voile de matière (34) est déchiré sous la pression (42) du deuxième matériau, un passage (35) pour le deuxième matériau étant alors formé au travers de l'élément. Elle concerne également une pièce de structure de véhicule automobile.
