Abstract Lattice sandwich structures are widely used in aerospace, automotive and marine fields because of their excellent mechanical properties, outstanding energy absorption capability and unique functionality. While, traditional lattice materials have problems of uneven stress distribution and joint stress concentration. In order to solve the above problems, a new cosine function cell-base (CFCB) single-cell structure is proposed based on body-centered cubic structure (BCC). To study the energy absorption characteristics of CFCB lattice sandwich structure under out-of-plane compressive load, the CFCB lattice sandwich structure was prepared, and the quasi-static crushing test was carried out, and the test results were compared with those of BCC lattice sandwich structure. The results show that the load-bearing capacity and energy absorption capacity of CFCB lattice sandwich structure under out-of-plane compressive loading are obviously better than that of BCC lattice sandwich structure. Then, based on finite element model, the effects of cell parameters such as cell diameter, amplitude, period length and single cell layer number in the thickness direction of CFCB lattice sandwich structure on capacity absorption performance under out-of-plane compressive loading were simulation analyzed. The related research results are expected to provide a reference for the design of new lattice sandwich structures.
