  • Publication number: 20100139841
    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. The joined moulded parts are subsequently machined to achieve the desired final geometry or a geometry corresponding to the desired final geometry plus the machining allowance. Then, the carbon parts are available after carbonisation of the moulded parts in non-oxidizing atmosphere. 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.
