Abstract
In an aspect, a composite material system comprises: a structure having an architected three-dimensional geometry; wherein said three-dimensional geometry is monolithic and deterministic; and a matrix phase; wherein said matrix phase at least partially infiltrates said structure. In some embodiments, the three-dimensional geometry is a nano- or micro-architected three-dimensional geometry.
