Contact Thermoset Processing and Preforming
The development of efficient manufacturing processes which factor in in-
teraction between materials, processes and component properties has an
increasingly significant role to play in the field of heavy-duty fibre-reinforced
composite components based on thermosetting matrix systems. In addition
to robust processing techniques compatible with serial manufacturing tech-
nologies and rapid-hardening matrix systems demand for realization of indi-
vidualized lightweiht structures is particularly high.
Research at ILK's Expert Group on Thermosetting Processes and Preforming
Sirko Geller
focuses on the characterisation, modelling and simulation of reactive pro-
+49 351 463 42197 cesses, the engineering of systems and processes for innovative preforming
✉ sirko.geller@tu-dresden.de concepts and the development and refinement of novel materials, semi-fin-
ished products and corresponding processing technologies. The manufactur-
ing of active composite structures represents another area of research em-
phasis, which focuses on the targeted exploitation of the moderate process
conditions that characterise the processing of thermosetting matrix systems.
A comprehensive technological equipment enables the group's scientists to
make use of both prototypical and serial processing technologies. Areas of fo-
cus include filament winding and braiding, injection and pressing techniques,
additive manufacturing and pultrusion. Interdisciplinary cooperation with ILK's
other expert groups is the basis for consistent research in the different sub-
ject areas.

Contact Joining Technologies
In the conception, design and dimensioning of lightweight structures, the pro-
vision of suitable joining systems has a decisive importance. The aim of our
Expert Group is to identify the relevant problems in the field of joining tech-
nology at an early development stage especially with regard to multi material
design. Based on this, application-oriented joining solutions are identified
and investigated scientifically. For this purpose, both established technologies
are considered and applied to specific joining tasks as well as novel materi-
al-adapted joining methods are developed. The Expert Group pursues a holis-
tic, material-independent development approach. It includes the technological

basics, the material-structural phenomena in joining zones and the modelling

One main research focus are intrinsic joining zones, which are formed in hy-
brid structures during component manufacturing: e.g. when overmoulding
laser-structured or plasma-treated surfaces. Extrinsic joining zones, which
enable the integration of hybrid structures into the system environment, are
another focal point: e.g. the novel joining process Hotclinching. In addition,
we develop novel methods for the analysis and description of the local com-
posite material structure in joining zones for the design and dimensioning of
joining systems: e.g. for inserts embedded by warm forming.
