Application and key technology of composites tank in space cryogenic propulsion system

Research and development of composites cryogenic tank for areospacecraft is a complex engineering technology involving several subject disciplines. Cryogenic propulsion system is an important research direction, due to the high emphasis paying on reducing vehicle weight for space transportation systems. Advanced carbon fiber reinforced composites (CFRPs) are primary candidates for structures, and CFRPs cryogenic tank became the important research project in the space power. One potential application of CFRPs is in the construction of cryogenic fuel tanks for next-generation reusable launch vehicles (RLV). The development process and research of several type composite cryogenic tanks in the field of aerospace vehicle are introduced, and the technical problems of composite cryogenic tank which need to be solved are summed up.
