Abstract: A method for manufacturing multilayered truss cores, which solves, among other things, key issues of bonding monolayered truss cores to one another. A multilayered truss core may be created from a single planar perform of an appropriate geometric pattern. Once the desired preform is manufactured it is then deformed into a three-dimensional (3D) truss network. This approach bypasses the need to stack and join monolayer truss cores, eliminating the additional tooling, lay-up, and interlayer bonding process steps. These multilayered cores may then be attached to facesheets or the like to form multilayered truss core panels or other multifunctional structures.
