Fiber metal abradable seals are used to control clearances in the compressor and turbine sections of gas turbine engines. Fiber metal seals are good abradables that rub by the low energy mechanism of brittle fiber fracture over a wide range of rub conditions. Rub mechanisms are significantly influenced by features in the seal microstructure.

High temperature fiber metal seals have been developed with temperature capability to 1650°F (1170 K). These seals have been characterized to determine abradability, mechanical properties, temperature resistance and permeability.
