Abstract
A tow of carbon fibres was coated with copper, nickel and cobalt by the cementation process. Conditions were optimized to obtain continuous, uniform and adherent coatings on three types of carbon fibres. The surface of the carbon fibres was activated by heating in vacuum at 700° C for about 15 min. The fibres were suspended in an aqueous solution of metal (Cu, Ni, Co) salt which also contained glacial acetic acid. To the solution a displacing agent such as Mg, Al, Zn or Fe was added. The metal was displaced from the solution and plated onto carbon. The thickness of the coating was dependent on the metal salt solution concentration and concentration of the surface activator (glacial acetic acid) in the solution. The appearance (dullness or brightness) of the metal coating was dependent on the concentration of the activator and the amount of displacer metal added. Mechanical testing of the single fibres indicated that the strength and modulus of the coated fibres was dependent on the coating thickness. In general, an increase in the coating thickness decreased the mechanical properties of the coated fibres. The coated fibres were introduced into an aluminium matrix successfully by the vacuum-infiltration technique to obtain composites with a uniform distribution of fibres.
