  • Assemblies formed by additive manufacturing, radar absorbing structures, and related methods
    Patent number: 11135763
    Abstract: An assembly formed by additive manufacturing comprises a top face sheet, a bottom face sheet, and a core structure between the top face sheet and the bottom face sheet, the core structure comprising a plurality of cells, wherein structural elements of the core structure defining the plurality of cells exhibit at least one electrical property in at least one direction varying from at least one electrical property in a second, different direction and at least one structural property in at least one direction varying from at least one structural property in a second, different direction, wherein at least a portion of the structural elements comprises a radar absorbing structure, the structural elements comprising a matrix material and at least one additive dispersed in or on the matrix material. Related radar absorbing structures and related methods of fabricating the radar absorbing structures are also disclosed.
