Using scaled model experiments to predict the response of full-scale engineering structures under impact loads has the advantages of being economical， efficient， and feasible. As lightweight， high strength composite materials are widely used in large-scale aerospace structures， the study of the impact similitude theory and scaling methods for composite materials is becoming increasingly important. For the similarity scaling problem of elastic laminate under impact response， conventional scaling methods usually fail to work effectively due to the strict requirements imposed by geometric scaling factors and laminate ply orientation matching. This article combines the ODLV directional dimension impact similarity law system with elastic laminate constitutive equation， derives the impact similarity law of elastic laminates， and obtains laminate stiffness coefficient scaling factors which are described by the directional dimension. Based on the similitude relationship， a similitude distortion modified method is proposed. This method adjusts the ply angles of scaled models to achieve stiffness compatibility and modifies the impact velocity to achieve similarity in the elastic laminated plate impact response. It overcomes the scaling constraints inherent in traditional methods and can effectively address both material distortion and width distortion problems. Simulation results show that the scaled models have good similarity with the prototype structure in displacement， impact force， and impact energy response， which suggests that the designed scaled model under the instruction of the laminate impact similarity scaling method proposed in this article can effectively predict the impact dynamic response of the prototype structure.
