Abstract
The thermochemical and mechanical stabilities of graphite fiber/polyimide composites aged at elevated temperatures, (300°C and above), are a function of the strengths of the component materials and the fiber matrix interface region. The relationship between the chemical characteristics of the component materials and failed composites as determined by ESCA and the mechanical properties of the isothermally aged composites will be presented. The composites examined represent a series of graphite fibers of various moduli and strengths in a polyimide matrix, PMR-15, exposed to flowing air at 316°C for 2000 hours.
