INTERFACIAL REACTIVITY IN ALUMINIUM CARBON FIBER COMPOSITES/

The study of the interfacial reactions between carbon fibres and alumi nium has been performed using a mass spectrometer. Analysis of the gas eous species evolved by the fibres during heat treatment show that int erfacial reactions occur between some of these gases and aluminium. Th e products of these reactions are aluminium carbide and aluminium oxid es. The aluminium carbide produced during heat treatment has been quan titatively measured by determining the amount of methane produced upon the hydrolysis of the carbide.
