Aerospace applications
Aerospace applications put temperature, load, vibration, friction, wear, tight tolerances, and limited lubrication on the same small part. Dominion manufactures those parts in polyimide and aerospace-grade metals.
Potential applications
Aircraft engines, turbine engines, compressor assemblies, variable stator vane systems, fan systems, actuation, flight controls, landing-gear components, pumps, valves, hydraulics, fuel-system components, interiors, engine externals, APU systems, and ground-based turbine generation.
Questions engineers ask
Short answers
Is polyimide documented in aerospace?
Yes. NASA technical literature documents self-lubricating polymer composite bearings in aircraft control surfaces and bushings associated with variable stator vanes. DuPont identifies polyimide components for aircraft-engine bushings, bearings, thrust washers, and wear pads.
