| description | The invention relates to a solid rocket engine bonding interface aging and creep damage test method and a coupling model, and the method comprises the steps: designing a bonding interface test piece, carrying out bonding interface test piece creep tests after different aging temperatures and test time, obtaining holding load time under different creep stresses, introducing creep parameters considering the aging temperatures and time, and determining the bonding interface aging and creep damage of a solid rocket engine. And establishing a model of creep damage model parameters changing along with aging temperature and time to obtain a bonding interface aging and creep damage coupling model. The invention provides a test method and a model for characterizing the degradation process of the bonding interface under the action of aging and gravity load factors, and provides a basis for evaluating the damage of the bonding interface.
