Zusammenfassung:	The present disclosure is directed to an elastomer mixture formed from an ionic liquid epoxy (ILE) and a curing agent, such as T-403 polyetheramine, where the cured elastomer mixture remains tough yet rubbery and is compatible with use in cryogenic temperatures. As such, the cured elastomer is provided as one or more layer of a composite linerless storage structure for use in cryogenic environments and for storage of cryogenic fuels. The low glass transition temperature and low thermal expansion coefficient of the cured elastomer allow for resistance to micro-cracking in such conditions. Thus, the linerless composite storage structure is leak resistant. Additionally, the cured elastomer may be used as a sealant in cryogenic conditions.
