Abstract
This invention relates to lightweight containers for fluids under pressure. The container is formed from an outer shell of fibrous material impregnated with resin and an inner wall made of an alloy which has a temperature M.sub.s for reversible martensitic transformation which is higher than or equal to the normal mean temperature at which the container is used. The invention is applicable in particular to containers for storing and transporting gases at pressure higher than four bars.
Claims8
In a container for storing fluids at a pressure higher than atmospheric pressure, an outer shell formed by winding fibres of high specific mechanical strength impregnated with thermosetting resin to resist mechanical stresses set up by the fluid under pressure, and an inner wall of metallic material which forms an inner lining for the said shell and which provides a seal, said inner wall being made of a metallic material capable of undergoing a change in crystalline structure of the martensitic type and having a temperature for the appearance of the martensitic phase on cooling which exceeds the usual mean operating temperature of the container and ambient temperature.
