Process for the production of a carbide ceramic material, carbide ceramic material, pre-form for a carbide ceramic component and a process for preparing a starting material for a pre-form of a ceramic material

摘要

Short carbon fibres are used to make the starting material in a method (M1) for the production of carbide ceramic materials, especially silicon carbide (I), by making a porous precursor from a starting material (SM) containing cellulose powder, pyrolysing the precursor to an open-pore material and converting this into (I) by infiltration of silicon-containing materials. Independent claims are also included for (1) carbide ceramic materials, especially (I), with short carbon fibres (SCF) embedded in a Si/SiC-rich ceramic matrix (2) components of structural and/or functional ceramic made from (I) (3) precursors as defined above (II) for such components (4) a method (M2) for the production of starting material for (II) by moistening and then granulating a dry powder mixture of the required materials .
