this report documents the results of an in-house program to determine what type of interactions occur between graphite reinforcing fiber and the polymeric matrix in advanced composites and how these interactions effect interfacial mechanical properties and durability. surface treatments applied to type a fiber of pan-based material increase the surface energetics as measured by krypton adsorption on 30 of the surface. in addition, the affinity of the treated surface is increased for adsorption of typical ambient gases over the untreated surface by a factor of eight. finally, the surface of this fiber contains a significant amount of sodium which affects the fiber surface properties
