Abstract
A coated carbon-carbon composite of the kind incorporating carbon fibres in a carbon matrix also incorporates in at least a region (2) thereof other fibres of a different axial coefficient of thermal expansion from that of the carbon fibres, the other fibres being arranged in relation to adjacent carbon fibres so as to provide in combination with the carbon matrix a coefficient of thermal expansion of that region (2) of the composite which is compatible with that of an anti-oxidation coating (1) on the surface of that region.
