ABSTRACT:
An airfoil used in a gas turbine engine exposed to high temperatures, the airfoil having a TBC layer that includes fibers of reinforcing material to add strength to the layer of TBC. The fibers are made from a similar material in which the airfoil is made from to withstand the high temperatures, and have a diameter of about 0.1 mm in order that a thin layer of TBC can completely cover and embed the fibers within the layer.
