A polymer composition that comprises from about 20 wt. % to about 70 wt. % of a polymer matrix that includes a polyimide; from about 10 wt. % to about 50 wt. % of inorganic fibers; from about 5 wt. % to about 30 wt. % of a flame retardant system that includes an organophosphorous compound; and from about 0.1 wt. % to about 5 wt. % of a stabilizer system that includes a heat stabilizer is provided. The heat stabilizer includes a copper compound. The polymer composition exhibits an initial tensile strength and an aged tensile strength after exposure to temperature of 200° C. for 1,000 hours. The ratio of the aged tensile strength to the initial tensile strength is about 0.5 or more.
