Abstract
Polyimide resin compositions that contain an end-capped rigid aromatic polyimide, graphite and, optionally, a filler selected from sepiolite, attapulgite, kaolinite, or a mixture thereof, are found to exhibit low wear at high temperatures. Such compositions are especially useful in molded articles that are exposed to wear conditions at high temperatures such as aircraft engine parts.
