    Abstract: The invention concerns a method for metal coating of fibres (15) by liquid process, said method being particularly but not exclusively designed for coating in thick and even layers (22) with metals and metal alloys having high melting point and reactivity. Said method is characterised in that it consists in moving along the stretched fibre (15) in the liquid metal maintained in levitation in a well (1), said fibre (15) passing through orifices (6, 7) provided in the well (1) wall (3), said orifices (6, 7) being arranged on either side of the liquid metal at places where the liquid metal (10) is not in contact with said wall (3).

    Abstract: A ceramic fibre is made by spinning a plurality of polymeric materials each including at least one ceramic precursor into a composite fibre, and then pyrolysing the composite fibre to form a composite ceramic fibre of non-homogeneous composition. A preferred ceramic material for use in this method is made by pyrolysing an organo-metallic compound dispersed in an organic polymer carrier. The principal products are tailored matrix-compatible ceramic fibres for reinforcements, and have a core-sheath structure made by coaxial spinning methods. A core of desired mechanical properties, such as silicon carbide, is given a chemically appropriate surface layer. Transition metal compounds are preferred, in a range of organo-metallic ceramic precursors that include carborane derivatives. Allowed additives include metal-silicon compounds, other ceramics, corresponding metal oxides and elementary metals.
