• In this paper, two types of the composite XX-type lattice sandwich structure (XX (Ⅰ) and XX (Ⅱ)) were made of panels (medium-density fiberboard and plywood) and core (birch) by using a type of insertion-glue method. An out-of-plane compressive test and a short beam shear test were carried out to investigate the failure modes, mechanical and energy absorption properties of the composite XX-type lattice sandwich structure. Results showed that the compression and short beam shear failure modes of composite XX-type lattice sandwich structure were mainly the shear failure of the core and the failure of panels. The sandwich structure with the core diameter of 8 mm had good compression property. The XX (Ⅱ)-type lattice sandwich structure of the combination of Plywood + birch had better compression, short beam shear, and energy absorption properties. The combination of MDF + birch was more suitable for the compressive theoretical model. •Mechanical and energy absorption properties of the combination of Plywood + birch was significantly improved.•The specific strength and specific energy absorption were analysed.•Theoretical models were established to study the compression and short beam shear properties.
