Abstract: The invention relates to a method for the manufacture of a ceramic component of desired final geometry using at least a cellulose-containing semi-finished moulded part, which is pyrolysed in non-oxidizing gas atmosphere. In order to manufacture complex components, it is suggested that at least two semi-finished moulded parts are firmly joined either in raw form or after at least partial carbonisation.

Alternatively, these can be converted into a CMC composite material in a non-oxidizing gas atmosphere by a metal infiltration process with simultaneous reactive joining of at least two moulded parts.
