Calculation Methods and Simulation Contact

The development of modern lightweight structures requires scientists to ex-
haust the whole potential a material has to offer while also enhancing the
level of cost efficiency achieved. Computer-aided methods can make a deci-
sive contribution to this and will become even more important in the devel-
opment process and an more central element of the development process in
the future. Therefore, linking the calculation methods along the entire value
chain plays a key role.

The focus of the work in the scientific area CMS lies in the development and
realization of practice-oriented methods combining multi-process, multi-ma- Dr.-Ing. Bernd Grüber

benefit from the broad expertise of the ILK in the fields of experimental anal-
ysis, process engineering and design and incorporate this know-how directly
into both the model development and the results evaluation processes. So,
the design process, which is largely shaped by the complex interactions be-
tween material, production, joining and system behavior, can be made more
robust, precise, and efficient.

Our goal is to synergistically exploit the currently insufficiently used high mate-
rial-specific potential of new materials and construction methods, for example
through digital twins. We combine in-house developed simulation and analysis
methods with commercially available software solutions. Dr.-Ing. Andreas Hornig

Thermoplastic Processing Contact

The manufacturing of promising lightweight structures demands the availabil-
ity of efficient and networked process chains. With this in mind, the research
carried out by the Expert Group on Thermoplastic Processes targets maxi-
mum efficiency throughout the entire value chain and the ambitious goal of
a closed material cycle with simultaneous reduction of energy requirements.

To this end, the expert group manages a complex process network starting
with the development, manufacturing and characterization of novel semi-fin-
ished thermoplastic goods with tailored characteristics, for example com-
pounds, films, tapes and organosheets. Subsequently, new preforming tech- Tobias Lebelt

hollow structures. The process chain ends with the development of efficient
manufacturing processes based on injection molding, compression molding,
pultrusion, extrusion and generative techniques. The unique machine park
available at ILK's Process Development Centre enables the group's scientists
to set up and test fully automated networked, robust process chains under re-
alistic serial manufacturing conditions. The activities draw on longstanding ex-
perience and extensive know-how gained in connection with the development
of innovative tooling, automation and processing techniques for the efficient
manufacturing of hybrid thermoplastic structures. The group's process devel-
opment activities are supported by the use of continuous process simulation.
