Laminate air seal for a gas turbine engine

A seal assembly for a gas turbine engine to seal air flow between a first engine part and a second engine part, the seal assembly comprising:

• a laminate configured to attach to the first engine part and comprising:
• a composite of a plurality of fabric layers, each layer of the plurality of fabric layers stable at an operating temperature of the gas turbine engine and including one layer of carbon disposed between two layers of fiberglass;
• a polymeric resin stable at the operating temperature of the gas turbine engine, wherein the resin is cured and thereby bonds the plurality of fabric layers together to form the laminate;
• and
• a lubricant coating bonded to a surface of the laminate to add lubricity between the laminate and an underlying wear strip to reduce wear on the second engine part caused by the laminate.

A method of forming a laminate seal for a gas turbine engine, the method comprising:

• preparing a composite of a plurality of fabric layers and a polymeric resin, wherein the fabric layers include-one layer of carbon disposed between two layers of fiberglass and the fabric layers and the polymeric resin are stable at temperatures greater than 205 degrees Celsius;
• curing the resin such that the composite forms a laminate;
• bonding a lubricant coating to the laminate to reduce friction between the laminate and a second part of the gas turbine engine;
• and
• attaching the laminate to a first part of the gas turbine engine to seal a gap between a first part and the second part of the gas turbine engine.
