Problems solved by technology

Although the strength of this type of hybrid part is suitable for semi-structural parts, the strength of this type of hybrid part may prove insufficient to withstand impacts, especially for structural parts of the motor vehicle chassis such as central pillars, pillars A or C, longitudinal Outer side members, roof rails, impact beams or any other vehicle structural member

Embodiment Construction

[0095] figure 1 A central structural pillar 10 of a motor vehicle is shown, comprising:

[0096] - shaped metal material sheet 12,

[0097] - shaped composite material panels 14,

[0098] - A molded polymer material 16 which at least partially covers the cladding metal material plate 14 covered with the composite material plate 14, the polymer material 16 optionally forming ribs 18.

[0099] The metal material plate 12 is in the form of a hollow part and has a concave inner surface 12a and a convex outer surface 12b.

[0100] The composite material sheet 14 covers the face 12 a of the metal material sheet 12 . The composite sheet 14 contains several layers of fibers impregnated or embedded in a polymer matrix.

[0101] It should be noted that the invention is not limited to a particular shape of the face 12a of the sheet of metal material 12 on which the sheet of composite material 14 is applied, which face 12a may be a convex face or otherwise.

[0102] The polymer mater...

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.

Description

technical field [0001] The invention relates to a method for producing a hybrid structural component of a motor vehicle and to a corresponding hybrid structural component. Background technique [0002] The term hybrid structural component refers to a structural component formed from several different materials, especially a metallic material and one or more polymeric materials. [0003] Certain structural components of motor vehicles are particularly stressed during impacts and must be able to absorb a portion of the impact energy in order to maintain the structural integrity of the vehicle. Such structural members must also be strong enough to withstand various structural functions. For example in the case of a motor vehicle center pillar, which is subjected to a high degree of stress during a side impact and must also hold the rear doors via their hinges and resist the front doors by their closing systems. [0004] In addition, manufacturers are making motor vehicle stru...
