Abstract
The invention relates to a method for producing a multi-material composite (4) and a multi-material composite (4). Due to the abrupt change
in material properties at the interface between different materials, in particular metallic and polymeric materials, cracks often develop in multi-material
composites, the service life thereby being shortened. The method according to the invention is based on a gradual adjustment of the material properties
of the materials of a multi-material composite (4) at the interface. Under the influence of elevated temperature or elevated temperature and elevated
pressure, a composite is formed from at least one metal layer (1), at least one fiber-reinforced or unreinforced first polymer layer (2) and at least one
fiber-reinforced or unreinforced second polymer layer (3), which is formed from the polymer of the first polymer layer (2) and nanoparticles and which at
least in some regions is arranged between the metal layer (1) and the first polymer layer (2), nanoparticles of the second polymer layer (3) diffusing into
the first polymer layer (2) such that a gradient layer (5) is formed, in which the nanoparticle concentration decreases toward the first polymer layer (2).
The multi-material composite (4) produced by means of the method according to the invention has a particularly long service life and can be used, for
example, in drive shafts for the aviation industry, automotive industry or maritime industry.
