The PCS melt is squeezed out through the spinneret at a pressure of 1.5-4.0 MPa to form a polymer fiber. It is gradually cooled in an inert atmosphere to room temperature, followed by curing. At the second stage, thermal-oxidative crosslinking is performed. At the third stage, carbonization of the resulting cured polymer fiber is carried out with its transfer to the ceramic phase. At the fourth stage, the resulting silicon carbide fiber of β-modification is dressed.
