Abstract

Polyimide resin compositions that contain an aromatic polyimide, graphite and a sepiolite filler, or a mixture of a sepiolite filler and a kaolin filler, are found to exhibit low wear and high thermal oxidative stability. Such compositions are especially useful in molded articles that are exposed to wear conditions at high temperatures such as aircraft engine parts.
