Abstract

In one aspect, a material is disclosed, including: a periodic structure including a plurality of unit cells, the plurality of unit cells having a respective plurality of shared nodes, wherein each of the plurality of unit cells has a plurality of members forming an open cell volume; and a matrix material associated with the periodic structure. In another aspect, a method of forming a material is disclosed, including: forming a periodic structure including a plurality of unit cells, the plurality of unit cells having a respective plurality of shared nodes, wherein each of the plurality of unit cells has a plurality of members forming an open cell volume; and associating a matrix material with the periodic structure. Matrix material selection, composition, manufacturing, interfacial bonding modification, and post-treatments of the periodic structure-matrix material composites are disclosed.

First claim

The invention claimed is:

1. A method of forming a material, comprising:
forming a periodic structure including a plurality of unit cells, the plurality of unit cells having a respective plurality of shared nodes, wherein each of the plurality of unit cells has a plurality of members forming an open cell volume;
coating the plurality of unit cells with an adhesive; and
impregnating the open cell volume with a matrix material, wherein coating the plurality of unit cells with the adhesive promotes adhesion between the plurality of unit cells and the matrix material.

2. The method of claim 1 , further comprising selecting each member of the plurality of members from a group consisting of: a hollow tubular member, a solid tubular member, a coil spring member, a double spring member, a diamond member and a spherical hollow member.

3. The method of claim 1 , wherein the matrix material is porous.

4. The method of claim 1 , further comprising chemically treating the plurality of unit cells to increase a surface roughness of the plurality of unit cells to promote adhesion with the matrix material.

5. The method of claim 1 , wherein the matrix material is associated with periodic structure via at least one of: powder infiltration and sintering, compression molding, injection molding, extrusion molding, vacuum infiltration, vapor deposition, electrochemical deposition, casting, and brazing.

6. The method of claim 1 , further comprising applying a plasticizer, a lubricant, or a surfactant to facilitate impregnating the open cell volume with the matrix material.

7. The method of claim 6 , further comprising removing the plasticizer, the lubricant, or the surfactant from the periodic structure.

8. The method of claim 1 , further comprising treating the periodic structure or the matrix material via applying a coupling agent, mechanical entanglement, surface treatment, surface roughening, and applying a binder in the matrix material.

9. The method of claim 1 , further comprising heat treating the periodic structure after the periodic structure is formed.
