In the overall project, the following development achievements are being pursued:
- Application-oriented further development of towpregs
- Epoxy resin tapes and tolerance-compensating heat-conductive mats, specially developed for the tape-laying process
- Production of aluminum-foam sandwiches for floor sandwich structures with integrated cooling structures
- Casting integration of cooling channels in load-bearing structures
- New design techniques that combine these materials and technologies in a resource-efficient and application-oriented manner, for example through load-path-optimized fiber composites and optimization of the topology
- Thermally activated intumescent fire-protection coatings
In order to consolidate the individual developments and evaluate them in terms of resource efficiency, a specific application example was selected: the battery casing of an electric vehicle. It has to fulfill demanding requirements with respect to mechanical stress, thermal conductivity and fire protection. As a result, the performance capabilities of the new materials can be clearly demonstrated on the battery casing. The developments could subsequently also be deployed for other components, such as complex profile structures, tank systems or chassis components.
The primary contribution being provided to this project by the Fraunhofer WKI is the development of fire-protection coatings on the basis of lignin – a plant by-product of the agricultural and paper industries. This is being carried out in close cooperation with the partners LXP Group and Synthopol. We are thereby planning the following approach:
- Phosphorylation of lignin
- Formulation of intumescent fire-protection coatings using the produced binder systems
- Investigation of the fire-protection coatings with regard to their fire behavior, their mechanical properties and their weathering stability
