It introduces the characteristics and applications of lattice metallic materials and metallic foam materials among ultra-light porous materials, and points out their respective shortcomings. Subsequently, it elaborates on the research progress of lattice-foam composite structural materials at home and abroad, including the research achievements of research teams such as Xi’an Jiaotong University and the University of Virginia in the United States. Then, the key technologies in the preparation process of lattice-foam composite structural materials are discussed in detail, such as the rapid prototyping technology for special-shaped parts of porous materials, the friction stir welding technology for metallic foams, and the large-area joining and composite technology between the core and face sheets of composite structures. Finally, the research on lattice-foam composite structural materials is summarized and prospected.</abstract><keywords/></article-meta></front><body/><back><ref-list><ref id="B1" content-type="article"><label>1</label><element-citation publication-type="journal"><p>Evans A, 2001, Lightweight Materials and Structures.
