Hydrogen is seen as a key energy carrier for a future CO2-neutral society. The high energy density of liquid hydrogen (LH2) is advantageous for transport and for a number of applications, especially in the mobility sector. Within the framework of the national hydrogen lead projects of the BMBF [1], KIT [2] is working with project partners of the technology platform "TransHyDE" in the lead...

225. M3Or1A-02: Investigating the applicability of existing mechanical test standards for fibre-reinforced polymer matrix composites at cryogenic temperatures

Contributed Oral

In recent years, due to the emerging growth of industry sectors focused on achieving Net-Zero energy sources; the research, development, and application of fibre-reinforced polymer (FRP) composites in the cryogenic liquid storage and distribution fields has grown significantly. When exposed to extreme temperatures, FRP composites can exhibit significant changes in their properties, as reported...

382. M3Or1A-03: Development of measurement tools and protocols for shear strength measurements of cryogenic epoxy interfaces

Contributed Oral

Cryogenic epoxies must have application-relevant electrical, thermal, and mechanical characteristics for safe operation for the life of the device. Appropriate testing techniques and protocols are necessary for epoxy material selection and qualification. Epoxies for cryogenic applications need to be tested at the cryogenic conditions of the device. We have developed a novel test protocol to...

74. M3Or1A-04: Design and Analysis of Wavelength-selective Nanofibers as Compact and Lightweight Thermal Coatings for Cryogen Applications in Deep Space Missions

CEC-12 – Fundamentals: Thermal Properties and Theory/Numerical Studies

Contributed Oral

Passive thermal control is vital in space, especially for extended missions involving cryogen storage needing protection from sunlight. Long-term cryogen storage in space can be possible when the exterior thermal coating can reflect most of the incident sunlight. Additionally, high emissivity in the longwave infrared wavelengths allows passive cooling by taking advantage of low-temperature...

343. M3Or1A-05: Cryogenic material testing with gaseous hydrogen for hydrogen-electric aircraft propulsion

Fabien Ebling (Fraunhofer Institute for Mechanics of Materials IWM)

Contributed Oral

The development of hydrogen-electric aircraft propulsion offers a perspective for emission-free aviation. Liquid hydrogen, which is stored in cryogenic tanks at 20-30 K, is used as energy source and to cool the electric engine. This increases power density and efficiency of the electric engine. In this application, the components are exposed to low temperatures and direct contact to hydrogen,...

28. M3Or1A-06: Dimensional stability of cryotreated diaphragms of pressure transducers

Mr D.S. Nadig (Indian Institute of Science)

Contributed Oral

Measurement of cryogenic propellant pressures (liquid oxygen and liquid hydrogen) of rockets is very critical for their successful launch. These pressure measurements are carried out using integral diaphragms pressure transducers. Material is machined out from both ends of the circular rod made of precipitation hardened martensite stainless steel (APX4), such that thin circular diaphragm is...
