Abstract: The low-velocity impact properties of carbon fiber metal laminates with corrugated sandwich aluminum plates were studied. The deflection, load, energy and surface visual damage of corrugated laminates with different height differences under different impact loads and laminates with microscopic particles added between layers were explored. On the basis of adding corrugated aluminum plate in the core, particle modification was added to the surface of the prepreg strip to further improve the overall impact performance of the laminate. The impact tests of corrugated sandwich carbon fiber metal laminates were carried out with 15 J, 30 J and 50 J impact energy respectively, and the low-speed impact response of the laminates was studied. Under the three kinds of impact energy, the laminates with a height difference of 0.2 mm and the addition of nanocellulose show the best impact resistance, and the surface visual damage and internal damage of the laminates are the lowest. The difference is most obvious when the impact energy is 30 J. The peak contact force of corrugated laminates with nanocellulose reaches 8.2 kN, which is 9.3% higher than that of 7.5 kN with only 0.2 mm corrugated laminates, and also shows better energy absorption characteristics. The results show that the addition of corrugated aluminum plate in the core of the laminate can toughen and support the core of the carbon fiber metal laminate. The addition of nanocellulose can change the direction of crack propagation and improve the impact resistance of the carbon fiber metal laminate to a certain extent. The combination of the two makes the overall impact resistance.
