Abstract: A pipe for conducting a cryogenic fluid. The pipe includes a rigid outer tube at least partially made of a fiber-reinforced polymer, a gas-proof inner tube running within the outer tube, an insulation layer arranged between the inner tube and the outer tube, and at least one flange formed at a respective end of the inner tube. The at least one flange connects the inner tube with the outer tube. Also a pipe assembly with at least two such pipes which are connected or configured to be connected at their respective flanges, and an aerospace system with at least one such pipe.

Abstract: A tank for the storage of liquid or gaseous substances with a fiber-reinforced plastic sheathing, which limits at least one interior space for holding the materials to be stored. At least one circumferential section of the fiber-reinforced plastic sheathing comprises an evacuable sandwich structure, which completely encloses the circumferential section. As a result, the tank has a low weight with a high thermal insulation capacity. Furthermore, a reliable explosion protection of the tank is provided. Furthermore, a method for manufacturing a tank for the storage of liquid or gaseous substances is provided.
