Abstract (en)
[origin: WO2020074504A1] The invention relates to a hollow cylindrical carbon fiber construction, comprising a carbon fiber nonwoven, which is continuous between the inner lateral surface and the outer lateral surface of the carbon fiber construction all around. Said hollow cylindrical carbon fiber construction can be obtained by a method in which a hollow cylindrical starting fiber construction, which comprises a nonwoven that is continuous between the inner lateral surface and the outer lateral surface of the starting fiber construction all around, is subjected to a pyrolysis process.
