Hybrid Material Systems

Any material is marked by its specific properties and advantages. Depending on the requirements of the component anytime another material is the optimum. Due to the increasing complexity und manifold requirements for components the choice of a material is often related to penalties under certain conditions. To avoid this drawback an intelligent combination of different materials to a hybrid material system can be preferred in such a way that the specific advantages of each material can be obtained.

An example for such a hybrid material system are fibre reinforced metals. These metal matrix composites (MMC) consist of high strength ceramic fibres, which are embedded in a metal alloy. The fibres are increasing the strength and stiffness while the metal contributes formability and toughness.

As basis for the production of metal matrix composites (MMC) and for surface protection of metals several coating technologies are applied. Especially for coatings with titanium the affordability can be increased drastically by the usage of electrolytic processes.

Processes for fibre reinforced plastics are well established. However, these materials have limitations regarding toughness, and impact and erosion resistance. These disadvantages can be disminished by replacement of some fibre plies with metal foils. The result are so-called metal-plastic-laminates.
