INTERFACIAL BONDINGS IN GR(F) AL COMPOSITES

Physical bonding between the graphite fiber and the aluminum matrix in the graphite-fiber-reinforced aluminum matrix composite materials (Gr (f)/Al) was manifested by the extended fine structure analysis of the electron energy loss spectroscopy (EELS). Diffusion bonding due to the dissolution of carbon into aluminum was demonstrated with quantitativ e chemical analysis of EELS. Reaction bonding, morphology and distribu tion of the reaction product Al4C3 were studied by transmission electr on microscopy (TEM) and high resolution electron microscopy (HREM). Me chanisms of the effect of processing parameters on interfacial bonding s were also discussed.
