Method of manufacturing improved of a piece of a hybrid structure of a motor vehicle and the piece of a hybrid structure corresponding

摘要

A method for manufacturing a hybrid structural part of a motor vehicle, characterised in that it comprises the steps during which a step a involves shaping a sheet of metal material to form a metal part, a step b involves producing one or more moulded layers (3, 30) of thermoplastic or thermosetting material covering all or part of the surface area of at least one face of the metal part, and a step c involves locally depositing, on the moulded layer of thermoplastic or thermosetting material (3) covering all or part of at least one of the faces of the metal part (2), reinforcing strips (4) formed from unidirectional continuous fibres coated in a polymer matrix.
