Abstract: A one-piece stud has a central longitudinal side; a first longitudinal side joined at a 90° angle to the first end of the central longitudinal side; and a second longitudinal side joined at a 90° angle to the second end of the central longitudinal side. The central side has a first and a second planar surface joined by an acute isosceles triangular channel midway between. The first longitudinal side is formed of a third and a fourth planar surface joined by an acute isosceles triangular channel midway between. The second longitudinal side has a fifth and a sixth planar surface joined by an acute isosceles triangular channel midway between.

Abstract: Methods and systems to manufacture lattice-based sandwich structures from monolithic material eliminate the bonding process which is conventionally used to join lattice-based truss cores to facesheets to form sandwich structures. The bonded interface is a key mode of failure for sandwich structures which are subjected to shear or bending loads because the nodes transfer forces from the facesheets to the core members while the topology for a given core relative density dictates the load carrying capacity (assuming adequate node-bond strength exists). In one aspect, a core and related structures provide very low density, good crush resistance and high in-plane shear resistance. Another aspect of the truss structures may include sandwich panel cores and lattice truss topology that may be designed to efficiently support panel bending loads while maintaining an open topology that facilitates multifunctional applications.
