The Air Force Research Laboratory is developing a high-temperature, high-performance dielectric film for the aircraft capacitors. Capacitors are devices that store electrical charges. The new film, called Fluorene Poly Ester, is suitable for applications from -55 to 227C. Aircraft capacitors are the weakest link in an aircraft's power electronics system because of their limited operating temperature, according to Sandra Fries-Carr, one of two developers of the film at the Air Force Research Laboratory. The laboratory formed a partnership with Wright Technology Network for developing the film for capacitor manufacturers. Initial applications include military aircraft projects.
