A micro-truss based composite friction-and-wear apparatus with a three-dimensional ordered microstructure and a method creating the same. In one embodiment, the apparatus includes a filler material and a three-dimensional ordered microstructure. The three-dimensional ordered microstructure includes a plurality of first truss elements defined by a plurality of first self-propagating polymer waveguides and extending along a first direction; a plurality of second truss elements defined by a plurality of second self-propagating polymer waveguides and extending along a second direction; and a plurality of third truss elements defined by a plurality of third self-propagating polymer waveguides and extending along a third direction. The first, second, and third truss elements interpenetrate each other at a plurality of nodes to form a continuous material, the first, second, and third truss elements define an open space, the filler material occupies at least a portion of the open space, and the three-dimensional ordered microstructure is self-supporting.
