1. A composite material comprising:
a volume of a matrix material and a plurality of particles disposed within the matrix material, the particles having a geometric shape with a longest dimension and a shortest dimension different from the longest dimension; and
the volume has an anisotropic structure in at least two dimensions comprising:
a plurality of volume portions arranged in a mosaic pattern with adjacent volume portions abutting along an interface comprising a surface forming a common boundary between the adjacent volume portions, and
the particles within at least one pair of adjacent volume portions are disposed in orientations to form a herringbone pattern in a plane that is normal to the interface, in which the interface corresponds to a spine of the herringbone pattern, wherein the geometric shape with the longest dimension of the particles of a first volume portion of the at least one pair of adjacent volume portions is disposed at a first non-orthogonal angle with respect to the interface, the geometric shape with the longest dimension of the particles of a second volume portion of the at least one pair of adjacent volume portions is disposed at a second non-orthogonal angle with respect to the interface and mirroring the first non-orthogonal angle, and wherein the orientations of the particles in the at least one pair of adjacent volume portions selected so that a crack propagating on a crack propagation path through the first volume portion or the second volume portion of the at least one pair of adjacent volume portions stops at or deflects to propagate along the interface.
