    Abstract:

    Different from traditional welded aluminum鄄alloy tank, the design emphasis of composite tank is fo鄄
    cused on preventing leakage of propellant effectively, such as liquid hydrogen and oxygen, which based on the mecha鄄
    nism of micro鄄crack initiation and propagation in resin during the full service periods. Based on the structural features
    of aerospace composite tank, this paper summarized the resin matrix composite performance at low temperature, de鄄
    sign criteria of composite tank and primary structure design of tank. Finally, the application prospects of composite
    tank are also proposed.
