1. A method of making a multilayered truss core, said method comprising:
- providing a preform member of appropriate topology including a plurality of intersecting members, wherein nodes are formed at said intersections; and
bending said preform member to form a multilayer truss core, wherein;
predetermined selection of said plurality of said nodes remain at least substantially in or are bent at least substantially into a first plane, predetermined selection of said plurality of said nodes are bent at least substantially into a second plane distal from said first plane, and predetermined selection of said plurality of said nodes are bent at least substantially into a third plane distal from said first plane and opposite from said second plane, whereby said first plane is between said second plane and said third plane to form said truss core.

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.
