Abstract (en)
An insulator for applications such as the base of a cryogenic reservoir, consists of a padded assembly made up of at least one layer of felt (36) and a cryo-technical fabric (35) in a spherical dome shape, fixed to the base of the reservoir by a reinforcing system (37). An insulator for applications such as the base of a cryogenic reservoir, consists of a padded assembly made up of at least one layer of felt (36) and a cryo-technical fabric (35) in a spherical dome shape, fixed to the base of the reservoir by a reinforcing system (37). The fabric is in the form of a series of sectors joined by their radii to form a dome, and the layers of felt are joined to the dome by self-adhesive strips. The reinforcing system is made up of a series of flexible linear elements passed through loops on the fabric sectors and joined to a central element (43). The cryo-technical fabric has an M1 inflammability rating with a surface mass of under 250 g/sq m and a resistance to rupture with a traction of 77 K higher than 100 MPa in the weft direction.
