Mechanical behavior of the sandwich structures with carbon fiber-reinforced pyramidal lattice truss core
TL;DR: In this paper, the buckling and splitting of truss member was observed in the compressive and shear tests and no nodal failure was observed, and the predicted results showed that the mechanical behavior of the pyramidal lattice truss core sandwich panels depends on the relative density of core and the material properties of members.
