ABSTRACT = {Aluminum lattice structures have the advantages of lightweight, high specific strength/stiffness and excellent plasticity, while alumina ceramic lattice structures usually show high strength and significant brittleness. Therefore, alumina/aluminum interpenetrating composites can combine two distinct mechanical properties and show superior performance, which is beneficial to applications in aerospace and military industries. In this study, alumina ceramic lattice structures were prepared by additive manufacturing (AM) and used as infiltration skeleton. The molten aluminum was then infiltrated into alumina ceramic lattice structures. By this method, the alumina/aluminum ordered structure composites were prepared. Through mechanical experiments and finite element methods, the quasi-static compressive properties and energy absorption behavior of alumina/aluminum interpenetrating composites were analyzed. It was found that the metal aluminum acted as the matrix with good plasticity and ductile, and the alumina ceramic as the reinforcement showed high strength. Mutual mechanical interlocking and constraints between the ceramic and metal were beneficial to the improvement of mechanical properties and energy absorption behavior of ceramic/metal interpenetrating composites.},
