Reinforcement of ceramic matrix composites: properties of sic-based filaments and tows
Résumé
The chapter examines failure characteristics of silicon carbide fibers and their performances at intermediate temperatures <1000°C. Behavior at higher temperatures when creep dominates has been discussed in previous papers and books on fibers or ceramic matrix composites. Focus is placed on features of fast fracture of single filaments and tows, on strength degradation due to oxidation, and slow crack growth during static fatigue. Data on a wide spectrum of SiC‐based fibers of first, second, and third generations are reported.
