Summary
Polymer-derived SiC-based fibers with fine-diameter (∼ 10–15 μm) and high strength (∼ 3 GPa) were prepared with carbon-rich and near-stoichiometric compositions. The creep resistance of these fibers (as assessed by bend stress relaxation, BSR, measurements) could be improved significantly by annealing heat treatments in nonoxidizing atmospheres. Fibers also showed excellent strength retention after annealing heat treatments up to 1700°C for the carbon-rich fibers and up to 1950°C for the near-stoichiometric fibers. The near-stoichiometric fibers could be prepared with ∼ 3 GPa tensile strength and BSR creep behavior which was significantly better than previously reported for other types of polymer-derived SiC- based fibers.
