Abstract

Composite cryogenic tanks are thought as the dominating structural components to realize future reusable launch  vehicles. For several years we have developed a cryogenic tank lined with liquid crystal polymer (LCP). LCP has low  coefficient of thermal expansion and excellent gas barrier property and is used to prevent leakage of low molecular gas  passing through CFRP of a tank. These characteristics are suitable for the material of cryogenic composite tank liner. A sub-sized tank was manufactured, and helium leak test and liquid hydrogen pressure test were conducted to demonstrate LCP liner concept. A full-sized tank for RVT is now under manufacturing.
