Abstract

A method is proposed for producing a CMC-component (6) comprising at least the steps of pyrolizing (2) a green body (1; 10) made of a fiber (15)-reinforced thermoplastic material (14) and infiltrating (4) the pyrolized green body by a liquid carbide forming substance (31). The fibers (15) of the green body (1; 10) are arranged in one or several strands (16), each of these strands (16) having a main extension direction. The lengths of the fibers (15) of each strand (16) are larger than the overall length (L) of the green body (1; 10) along the main extension direction of this strand (16).
