Abstract
The invention concerns a method for producing a hybrid-structure part of a motor vehicle, comprising shaping of a sheet of metallic material, the provision of a sheet of composite material, application of a layer of connecting material on a face of said metallic material sheet or on a face of said composite material sheet, the shaping of a hybrid element by shaping said composite material sheet to the shape of said metallic material sheet and joining the composite material sheet to the metallic material sheet by means of said connecting material layer, and the production of rigidification elements by overmoulding using a polymer material.
Claims6
A hybrid-structure part of a motor vehicle comprising:
- a sheet of metallic material,
- a sheet of composite material, at least partly covering a face of the sheet of metallic material, the sheet of composite material comprising at least one layer of fibers impregnated or embedded in a polymer matrix, the at least one layer of fibers being selected from among a layer of unidirectional fibers and a layer of woven fibers,
- a polymer material, molded, at least partially covering the face of the sheet of metallic material which is at least partially covered with the sheet of composite material, the polymer material optionally forming ribs,
- characterized in that the sheet of composite material partially covers the face of the sheet of metallic material and in that the polymer material at least partially covers uncovered parts of the face.
