Abstract
A three-dimensional (3-D) composite structure has a 3-D lattice structure that includes a plurality of struts, a matrix phase surrounding the 3-D lattice structure, and a strain limiting structure positioned at or near a center of the 3-D lattice structure. The strain limiting structure is fixed to at least one of the plurality of struts. The 3-D composite structure can be made using additive manufacturing techniques.
