Embodiment Construction

[0019] figure 1 A cross-sectional view of a typical three-layer composite 2 is shown. In this embodiment, the composite material comprises a middle layer 4 made of soft, easily formable alloy steel and two outer layers 6, 8 made of high-strength or very high-strength Made of high strength alloy steel. The outer layers 6, 8 on both sides can be made of the same alloy steel. However, it is also possible for the outer layers 6 , 8 to consist of different steel alloys, for example in the case of an application of the composite material 2 in which the different sides are loaded to different degrees. In this embodiment, the thicknesses of the outer layers 6, 8 on both sides are substantially equal. Of course, it is also possible to make the thicknesses of the three layers 4, 6, 8 different from each other. The composite material 2 can also have a metallic and / or organic coating (not shown) on one side or on both sides. For example, an aluminum-based coating or lacquer coating i...

Abstract

The invention relates to a use of a multi-layer metal composite material, which is produced by way of roll-bonding and can be wound, in a vehicle structure, particularly a body structure. It is the object of the invention to provide a use of a metal composite material as an alternative to monolithic materials. The object is achieved in that the composite material is a lightweight composite material and comprises three layers of a steel alloy, wherein at least one of the layers is made of a steel alloy having higher strength or maximum strength.

Description

technical field [0001] The invention relates to the use of a roll-produced, rollable, multilayer metal composite material in the construction of motor vehicles, in particular in the construction of car bodies. Background technique [0002] The materials used in the construction of motor vehicles, in particular in the construction of the bodywork, generally have properties which satisfy the requirements placed on the materials used. The outer parts of a motor vehicle should, for example, have high strength in order to ensure the integrity of the bodywork even under load. At the same time, the outer layer part should also have good coating properties, so that it can function, for example, as a paint carrier. In addition, the material of the outer part must have good formability so that complex geometries of the outer part can also be formed without damage. According to the current state of the art, it is not yet possible to optimally fulfill all requirements in a single mate...
