摘要:
The invention relates to a method for the production of a carbon or a ceramic component based on carbon, using a cellulose-containing semi-finished moulded piece which is pyrolysed. According to the invention, homogeneous large-size ceramic components may be produced, whereby a cellulose-containing, semi-finished moulded piece comprising fibres, chips or strands of homogeneous density distribution and homogeneous structure is used as semi-finished moulded piece and is pyrolysed in non-oxidising gas atmospheres.
摘要:
The invention relates to a composite ceramic body and a method for producing the same. Said composite ceramic body comprises a fibre-reinforced core region containing carbon, and a surface region containing SiC. In order to produce a composite ceramic body having good long-term behaviour, the proportion of SiC contained in the body continuously, or essentially continuously, varies from inside the core region towards the surface region.

The invention relates to a method for producing a carbon element having a honeycomb-shaped structure. In order to be able to produce such carbon elements by means of a technically simpler method, a prefabricated element that is made of paper or fleece and is provided with said honeycomb-shaped structure is pyrolyzed and stabilized.

The invention relates to a method for the production of a ceramic substrate of a semiconductor component, characterized by the following steps: producing paper comprising at least cellulose fibers, and a filler and/or SiC to be carbonized; pyrolizing the produced paper; and siliconizing the pyrolyzed paper.
摘要:
The invention relates to a tribological fiber composite component especially in the form of a brake disk or clutch disk, comprising a structure that encompasses at least one TFP preform (60, 62) which is provided with at least one stressable layer of reinforcement fibers. Said structure is stabilized by separating material from the gas phase and/or is provided with a monomer and/or a polymer, is hardened and pyrolyzed.
