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 downhole system, comprising:
a filter element 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;
a matrix material filling the open cell volume formed by the periodic structure, the matrix material including a mixture of soft metal and fiber binders, wherein the matrix material is porous; and
an adhesive layer for coupling the matrix material to the periodic structure that transfers load between the matrix material and the periodic structure.

2. The downhole system of claim 1 , wherein each member of the plurality of members is selected 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 downhole system of claim 1 , wherein the periodic structure is formed by a process comprising of at least one of: three-dimensional printing techniques, micromachining, photolithography, projection microstereolithograpy, a layer-by-layer additive, and micromanufacturing process.

4. The downhole system of claim 1 , wherein the periodic structure comprises at least one of: stainless steel, aluminum, copper, brass, nickel, Inconel, a chemical resistant alloy, a shape memory alloy, alumina, hexanediol diacrylate (HDDA), and polymethyl(methylacrylate) (PMMA).

5. The downhole system of claim 1 , wherein the matrix material occupies 5% to 100% of the open cell volume of the plurality of unit cells.

6. The downhole system of claim 1 , wherein the matrix material is associated with at least one outer extent of the periodic structure.

7. The downhole system of claim 1 , wherein the matrix material comprises at least one of: a thermosetting material, a rubber, a thermoplastic material, graphite, cotton, asbestos, and fiber glass.

8. The downhole system of claim 1 , wherein the periodic structure is treated to increase surface roughness to promote adhesion with the matrix material.

9. The downhole system of claim 1 , wherein a periodic structure elasticity and a matrix material elasticity are complimentary.
