Problems solved by technology

[0008] A disadvantage of this known prior art is that during the filling process, in which, for example, gas is stored under high pressure and at high speed in the storage container, heat is generated which may possibly damage the inner wall of the storage container, as long as if it is made of polymer material

Embodiment

[0122] Blow-molded polyethylene having an MFI of 0.3 g / 10 min at 190° C. under a load of 2.16 kg was blow-molded to form an inner liner.

[0123] Blow moldable polyethylene has a density of 0.95g / cm 3 .

[0124] Blow-moldable polyethylene contains organic peroxides, which have a crosslinking temperature of 175°C.

[0125] After shaping, the blown hollow body is subjected to a temperature of 240° C. over a period of 5 min for crosslinking. For this purpose, the hollow body is held in shape by the supporting air against unintentional deformations.

[0126] After the hollow body has cooled, the hollow body is wound with carbon fibers, which are impregnated with epoxy resin, until a layer thickness of 15 to 45 mm is achieved.

[0127] The storage container thus produced can withstand a pressure of 1000 bar of the fluid stored therein. The storage vessel can be filled with hydrogen, wherein a pressure of 700 bar can build up within 3 to 5 minutes.

Abstract

The reservoir according to the invention for receiving a fluid, in particular under a pressure that is elevated relative to the surroundings, comprises a hollow body that is delimited by a wall having a multi-layered structure, and a device for feeding the fluid to and carrying the fluid away from the hollow body, and is characterized in that the inner layer of the wall contains cross-linked polyethylene.

Description

technical field [0001] The invention relates to a storage container for fluids, in particular fluids under elevated pressure relative to the environment, having a hollow body and means for supplying fluid to or removing fluid from the hollow body, said The hollow body is delimited by a wall, wherein the wall has a multilayer structure. [0002] The invention also relates to a method for manufacturing such a storage container. [0003] Finally the invention relates to a fluid supply system comprising at least one such storage container. Background technique [0004] Storage containers for containing gaseous or liquid media under pressure are known from the prior art, all of which have a hollow body with a multilayer wall. [0005] Such storage containers are used, for example, for the supply of internal combustion engines in motor vehicles, the storage container containing and supplying gaseous or liquid combustible materials. [0006] In this case, in particular gas is co...
