GRK 1378:  Manufacture, Machining and Qualification of Hybrid Material Systems

• Subject Area: Production Technology
• Term: from 2007 to 2011
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 19984935

The constructional and technical limits of monolithic materials have almost been reached. The mechanical and/or thermal limiting values of conventional materials (Al, Mg, Ti) used for light weight structures always lie, for most practical purposes, under those of the standard construction material steel. Where considerably higher concentrations of performance with simultaneous reductions in masses are demanded, it becomes clear that the solution can only be found by combining materials with the appropriately matched properties. Moreover, only by using hybrid materials it is possible to combine higher strength, plasticity, sufficient resistance to corrosion, wear resistance, low density or adjustable electrical and thermal conductivity in relation to the product's thickness. Hybrid material systems are understood to be a composite of several materials, which are of both similar and dissimilar types. These range from coatings, functionally graded materials or particle and fibre reinforced materials to assembled components.
The Research Training Group is to offer exceptionally qualified doctoral students the opportunity to work on their dissertation in the area of hybrid material systems. The Research Training Group's approach is to utilise available individual experience in order to advance the development of hybrid material systems by focusing on the areas of materials science, production technology, forming techniques and simulation. The initiators from the departments of materials science, forming and production technology of the universities of Hanover and Dortmund have teamed up as a group in order to properly engage this task.
