As part of this research project, laser welding of thermoplastic fiber-reinforced composites for aircraft construction is to be developed to such a level that it can be reliably used for secondary applications.

To remain competitive in the long term, the German aviation industry must respond to the growing demand for low-emission and, ultimately, zero-emission propulsion systems. Cryogenic hydrogen as an energy carrier, in combination with turbine- or fuel cell-based propulsion systems, represents a promising solution in this regard. In addition to suitable propulsion systems, the efficient and weight-optimized storage of liquid hydrogen (LH₂) plays a key role.
