Abstract
Official abstract text for this publication.
A gas turbine engine includes a plurality of circumferentially-spaced blades. The blades have a polymeric coating thereon. An abradable seal circumscribes the blades and includes a polymeric matrix with a dispersion of a nanolayer material.
First claim
Opening claim text (preview).
What is claimed is: 1. A gas turbine engine comprising: a plurality of circumferentially-spaced blades including a polymeric coating thereon; and an abradable seal circumscribing the blades, the abradable seal including a polymeric matrix with a dispersion of a nanolayer material, wherein the nanolayer material includes at least one of sheet-structured graphene that has a bonded network of carbon atoms in a 2-dimensional geometry or MXene that has a formula of M n+1 X n , and wherein the nanolayer material includes the sheet-structured graphene and the MXene. 2. The gas turbine engine as recited in claim 1 , wherein the polymeric matrix is silicone. 3. The gas turbine engine as recited in claim 2 , wherein the sheet-structured graphene has an atomic monolayer structure. 4. A case for a gas turbine engine, comprising: an annular support; and an abradable seal mounted on a radially inner side of the annular support, the abradable seal including a polymeric matrix with a dispersion of a nanolayer material, wherein the nanolayer material includes at least one of sheet-structured graphene that has a bonded network of carbon atoms in a 2-dimensional geometry or MXene that has a formula of M n+1 X n , and wherein the nanolayer material includes the sheet-structured graphene and the MXene. 5. A seal for a gas turbine engine, comprising an annular abradable seal including a polymeric matrix with a dispersion of a nanolayer material, wherein the nanolayer material includes at least one of sheet-structured graphene that has a bonded network of carbon atoms in a 2-dimensional geometry or MXene that has a formula of M n+1 X n , and wherein the nanolayer material includes the sheet-structured graphene and the MXene. 6. A composition comprising: a polymeric matrix; and a dispersion of a nanolayer material within the polymeric matrix, wherein the nanolayer material includes at least one of sheet-structured graphene that has a bonded network of carbon atoms in a 2-dimensional geometry or MXene that has a formula of M n+1 X n , and wherein the nanolayer material includes the sheet-structured graphene and the MXene.
