Abstract

A composite ceramic body includes a fiber-reinforced core region containing carbon, and a surface region containing SiC. In order to produce a composite ceramic body having good long-term behavior, the proportion of SiC contained in the body varies continuously, or essentially continuously, from inside the core region towards the surface region.
