Claims6
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 Mn+1Xn, and wherein the nanolayer material includes the sheet-structured graphene and the MXene.
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 Mn+1Xn, and wherein the nanolayer material includes the sheet-structured graphene and the MXene.
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 Mn+1Xn, and wherein the nanolayer material includes the sheet-structured graphene and the MXene.
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 Mn+1Xn, and wherein the nanolayer material includes the sheet-structured graphene and the MXene.
