ABSTRACT:
A ceramic fiber is made by spinning a plurality of polymeric materials each including at least one ceramic precursor into a composite fiber, and then pyrolysing the composite fiber to form a composite ceramic fiber 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 fibers 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 metals 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.
