METHODS OF PRODUCING A METAL AND CARBON FIBRE COMPOSITE

摘要

A process of producing a metal and carbon fibre composite in which carbon fibres are treated to produce a very thin coating on the surface and the treated fibres are then wetted by metal melts to which a particular alloying metal has been added. The fibres are treated with a metal carbide and the alloying metal is preferably of the same metal as that of the carbide. The carbon fibres are infiltrated into the matrix metal while the latter is in a molten state and the invention is particularly concerned with the production of a wetting interface between the metal alloys and the carbon fibres. The method enables shaped bodies such as shaft bearings to be made in a convenient manner. The composite may have other forms such as continuous tapes for subsequent assembly into more complex shapes.
