More efficient production and cost minimization is being achieved with the use of actuators and sensor-equipped, reusable vacuum bags and component moulds for the production of complex lightweight components and semi-finished products using the vacuum infusion process within the project ‘logischer — Digital manufacturing process management in the production of lightweight fibre composite parts’. The integration of actuators and sensors in component moulds enables the vacuum infusion process to be controlled. More…

HOPAR
In HOPAR, demonstrators featuring a leading edge made from innovative hightemperature CFRP are being developed to address technical issues through construction and flight testing. This, in turn, minimises the development risk. Figure 1 illustrates the process route, ranging from the definition of the key constraints through to the selection of
materials and processes, and finally to the finished demonstrator. More… -
SEHRKALT
The goal of the SEHRKALT collaborative project is to develop, integrate, and validate cryogenically compatible fiber Bragg grating (FBG) sensors for monitoring CFRP cryogenic tanks for liquid hydrogen. The sensors are designed to enable high-precision temperature and strain measurements in the temperature range from 20 K to 120 K and to be permanently integrated into CFRP structures. In addition to sensor design, suitable integration and connection concepts are being developed, and guidelines for the evaluation and cryo-aging of fiber-optic sensor systems are being formulated. In this way, SEHRKALT lays the foundation for a reliable SHM system for LH₂ tanks and supports the introduction of hydrogen-based propulsion technologies in aviation. More…

LeiPoly
The spinning solution is prepared by mixing the polymer PANI with a suitable solvent. A dopant is also added to impart conductivity. This process converts the non-conjugated molecular structure of PANI into a conjugated form through doping. The fibers are extruded using wet spinning in a solvent in a system specifically designed for temperature-sensitive polymers. The fiber is precipitated in a coagulation bath, and the remaining solvent is washed out in a subsequent washing and stretching bath. More…

TEXAS
The goal of the project is to develop a purification process for removing lead from drinking water that, compared to existing methods, is energy-efficient, produces as little waste as possible, is flexible in application, and requires minimal maintenance. Alginates serve as the starting material; these form gels in the presence of calcium cations and are used in many technical applications, such as in the food and medical technology industries. More..

VibroSenLH2
The goal of the project is to develop a component-integrated sensor system for structural monitoring of fiber-reinforced plastic composites in liquid hydrogen tanks. The project involves the development of active and passive structure-borne sound technologies for real-time monitoring under cryogenic conditions. The result is an intelligent sensor system that can reliably withstand both the manufacturing process and varying loads. More…

rPLA-Garn
The “rPLA Yarn” research project aims to develop a recyclable yarn from industrial and consumer waste of the bioplastic polylactide (PLA). In the first phase, the quality of the PLA waste is analyzed and optimized through compounding. In the second phase, yarns with textile-grade strength are developed using the melt-spinning process. More…

HYTANK
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. More…
