Using polymer matrix composites to make cryogenic propellant tank of launch vehicle can significantly improve the launch capability of launch vehicle and reduce the launch cost. Not only must polymer matrix composites used in these applications be very structurally efficient

they must also contain extremely volatile cryogenic propellants. These requirements put forward high requirements for materials selection

tank structure design and manufacturing process. In this paper

the current research status of polymer for cryogenic use and the application of advanced composites manufacturing technology in composites cryogenic tank are summarized. Moreover

future research direction has been proposed to promote the practical engineering application of composites cryogenic tanks.
