Method of production of hollow bodies out of fibre reinforced ceramic materials

摘要

Production of hollow bodies made from fiber-reinforced ceramic materials comprises forming compressible cores having a shape corresponding to geometry of the hollow body being produced, forming a green body by filling a mold with the cores and a composition containing a pressable binder and fibers, pressing the fiber-containing composition so that the core is compressed in the pressing direction by 5 % of its expansion in the pressing direction, hardening and carbonizing the solidified green body by heating in a non-oxidizing atmosphere at 750-1100 degrees C to form a C/C body. An Independent claim is also included for a hollow body produced by the above process.
