The invention discloses a rolling compounding method for an aluminum /
magnesium /
titanium three-layer
composite plate. The characteristics of high strength of
titanium alloy,
low melting point and good vibration reducing performance of
magnesium alloy, good
plasticity and space
adaptation of the aluminum
alloy, and the like, are utilized and the excellent characteristics of respective component metals are combined by the aluminum /
magnesium /
titanium three-layer
composite plate provided by the invention, so that the high-speed
impact damage resisting property which the component metals do not own is acquired. Through the control on the ratio and interface of the aluminum alloy, the
magnesium alloy and
titanium alloy, the degree of fragmentation, melting and atomizing of shred cloud after the buffer
composite plate is subjected to high-speed
impact is changed and adjusted, so that the form of the shred cloud is changed, the degree of
impact damage to a backplate is reduced, and the high-speed impact damage resisting property is increased. The aluminum / magnesium / titanium three-layer composite plate is applied to an outer layer buffer plate in an outer layer protecting structure of an
aerospace vehicle and can be used for replacing a traditional single aluminum alloy material. The space
environmental effect and protecting level of the
space vehicle are increased; the design level of the
space vehicle are greatly promoted, and the service life of the
space vehicle are greatly prolonged.
