Tanks for liquid hydrogen
The project "LH2-Tanks" aimed at developing lightweight composite tanks for liquid hydrogen for future fossil free aircraft. The challenge is the extremely low temperatures and the large deformations and stresses they cause. The project included material testing, model development, design and manufacture of the tanks.
Hydrogen is a promising fuel for fossil free aviation, but must be stored in liquid form at extremely low temperature to give tanks with sufficiently low weight and temperature. The aim is to develop the technology for such tanks for the European aircraft industry.
The low temperature (-253°C) causes large thermal stresses and deformations in the material, which must be considered in the design. The change in material properties at low temperatures must also be measured. The project involved material testing, design, manufacture, and testing of two demonstrator tanks.
Composite materials with carbon fibre reinforced plastics allow lightweight tanks suited for aviation. Very thin composite plies manufactured by the Swedish company Oxeon are required to prevent that the thermal stresses cause cracking. Furthermore, the fibres have to be oriented appropriately.
