Abstract
Material from a fibre composite ceramic, constructed from a) a dense fabric or cluster of three-dimensional oriented fibres with a high thermal conductivity, b) a crystalline matrix of β-silicon carbide, that is produced in a CVI process on the fibres, c) a matrix component of β-silicon carbide that in a polymer infiltration and pyrolysis process is generated in pores of the fabric structure, starting from a suspension of silicon carbide powder in a polymer, and d) a further matrix component of β-silicon carbide that is created in a CVI process in cracks and pores of the material, caused by the preceding pyrolysis process.
