Abstract:
1. A method for attaching elastomeric material to two sides of a composite part, the composite part comprised of a matrix and at least one layer of woven fiberglass, the method comprising: calendering a first elastomeric material into a first elastomeric layer having a thickness that is more uniform than the first elastomeric material prior to the calendering; vulcanizing the first elastomeric layer to a first composite shim comprising three layers of woven fiberglass and four layers of adhesive, wherein the first composite shim is less than 0.0025 inches thick after the vulcanizing; bonding the first composite shim to a first side of the composite part using at least one of the four layers of adhesive of the first composite shim, wherein the first composite shim has a higher elastic limit than the composite part and at least one of the four layers of adhesive of the first composite shim is on a side of the first composite shim opposed to the first elastomeric layer; calendering a second elastomeric material into a second elastomeric layer having a thickness that is more uniform than the second elastomeric material prior to the calendering; vulcanizing the second elastomeric layer to a second composite shim comprising three layers of woven fiberglass and four layers of adhesive, wherein the second composite shim is less than 0.0025 inches thick after the vulcanizing; and bonding the second composite shim to a second side of the composite part opposite the first side using at least one of the four layers of adhesive of the second composite shim, wherein the second composite shim has a higher elastic limit than the composite part and at least one of the four layers of adhesive of the second composite shim is on a side of the second composite shim opposed to the second elastomeric layer.
