MATERIAL AND DEVICE FOR THE CONTAINMENT OF CRYOGENIC LIQUIDS

摘要

A composite material for manufacturing a device for containment of a cryogenic liquid and a device for containment of a cryogenic liquid which comprises at least one layer made of this composite material. The composite material is obtained from a composition comprising, in percentages by weight relative to the total weight of the composition: from 60% to 90% of a polyamide chosen from polyamides 6, 6.6 and 6/6.6 and mixtures thereof; from 10% to 30% of a primary synthetic graphite in the form of particles; and from 0% to 10% of an anti-oxidant. Applications: manufacture of cryogenic tanks and notably liquid oxygen tanks, particularly for a space launcher, manufacture of supply lines of cryogenic liquids and particularly liquid oxygen; manufacture of any device for the storage, transport and/or supply of a gas under pressure.
