A downhole expandable liner hanger positioned in a subterranean wellbore may comprise a liner. The downhole expandable liner hanger may further comprise an expansion element. The expansion element may comprise one or more annular seals bonded to the expansion element, a first spike; and a second spike. The downhole expandable liner hanger may further comprise a woven mesh, wherein the woven mesh is disposed around the expansion element between the first spike and the second spike, wherein the woven mesh comprises a first material layer and a second material layer. ## Claims ### Claim 1 A downhole expandable liner hanger positioned in a subterranean wellbore, comprising: a liner; an expansion element, wherein the expansion element comprises: one or more annular seals bonded to the expansion element; a first spike; and a second spike; and a woven mesh, wherein the woven mesh is disposed around the expansion element between the first spike and the second spike, wherein the woven mesh comprises a first material layer and a second material layer. ### Claim 2 (depends on 1) The downhole expandable liner hanger of claim 1, wherein the woven mesh is disposed within the one or more annular seals. ### Claim 3 (depends on 2) The downhole expandable liner hanger of claim 2, wherein the one or more annular seals are bonded to the woven mesh through vulcanization. ### Claim 4 (depends on 1) The downhole expandable liner hanger of claim 1, wherein the first material layer and the second material layer comprise a metal. ### Claim 5 (depends on 4) The downhole expandable liner hanger of claim 4, wherein the metal is selected from a group consisting of a stainless steel, a carbon steel, a carbon alloy, a nickel alloy, and combinations thereof. ### Claim 6 (depends on 1) The downhole expandable liner hanger of claim 1, wherein the first material layer and the second material layer are woven together into a pattern, wherein the pattern is one selected from a group consisting of plain weave, oxford, twill, herringbone, dobby, satin, velvet, basket weave, jacquard, leno, or combinations. ### Claim 7 (depends on 1) The downhole expandable liner hanger of claim 1, further comprising a third material layer, wherein the third material layer is disposed between the first material layer and the second material layer. ### Claim 8 (depends on 7) The downhole expandable liner hanger of claim 7, wherein the third material layer is a solid sheet of material. ### Claim 9 (depends on 7) The downhole expandable liner hanger of claim 7, wherein the first material layer and the second material layer are pre-woven, wherein the first material layer and the second material layer comprise holes. ### Claim 10 (depends on 9) The downhole expandable liner hanger of claim 9, wherein the third material layer comprises strands of material disposed parallel to each other, wherein the third material layer is interwoven between the first material layer and the second material layer through the holes. ### Claim 11 A downhole expandable liner hanger positioned in a subterranean wellbore, comprising: a liner; an expansion element, wherein the expansion element comprises: one or more annular seals disposed around the expansion element; a first spike; and a second spike; and a bias fabric comprise multiple sheets of a fiber-reinforced composite, wherein the bias fabric is disposed around the expansion element between the first spike and the second spike. ### Claim 12 (depends on 11) The downhole expandable liner hanger of claim 11, wherein the bias fabric is disposed between the expansion element and the one or more annular seals. ### Claim 13 (depends on 12) The downhole expandable liner hanger of claim 12, wherein the one or more annular seals are bonded to the bias fabric through vulcanization. ### Claim 14 (depends on 11) The downhole expandable liner hanger of claim 11, wherein the bias fabric comprises a material selected from a group consisting of a poly-paraphenylene terephthalamide, a polyamide, an aliphatic polyamide, a semi-aromatic polyamide, a polyester, a polyolefin, a cellulose, a cotton, a wool, a silk, a linen, a hemp, and combinations thereof. ### Claim 15 A downhole expandable liner hanger positioned in a subterranean wellbore, comprising: a liner; an expansion element, wherein the expansion element comprises one or more annular seals bonded to the expansion element; and a woven mesh, wherein the woven mesh is disposed around the expansion element, wherein the woven mesh comprises a first material layer and a second material layer. ### Claim 16 (depends on 15) The downhole expandable liner hanger of claim 15, wherein the woven mesh is disposed within the one or more annular seals, wherein the one or more annular seals are bonded to the woven mesh through vulcanization. ### Claim 17 (depends on 15) The downhole expandable liner hanger of claim 15, wherein the first material layer and the second material layer comprise a metal, wherein the metal is selected from a group consisting of wherein the metal is selected from a group consisting of a stainless steel, a carbon steel, a carbon alloy, a nickel alloy, and combinations thereof. ### Claim 18 (depends on 15) The downhole expandable liner hanger of claim 15, further comprising a third material layer, wherein the third material layer is disposed between the first material layer and the second material layer. ### Claim 19 (depends on 18) The downhole expandable liner hanger of claim 18, wherein the third material layer is a solid sheet of material. ### Claim 20 (depends on 18) The downhole expandable liner hanger of claim 18, wherein the first material layer and the second material layer are pre-woven, wherein the first material layer and the second material layer comprise holes, wherein the third material layer comprises strands of material disposed parallel to each other, wherein the third material layer is interwoven between the first material layer and the second material layer through the holes.
