This paper reports on the tensile fracture behavior of fiber bundle (yarn) and woven fabric of the Si-Ti-C-O fiber with 11 μm diameter, 3.6 GPa of tensile strength and 186 GPa of Young's modulus. The yarn of 662-765 filament and fabric showed a stable pseudoductility with the tensile strength of 752-1714 MPa and 522-1274 MPa, respectively. The elongation at fracture (1.2-1.9%), fracture energy (141-482 kJ/m2) and Weibull modulus (4.29-4.45) were similar for the yarn and fabric. The pseudoductility of yarn and fabric was analyzed using the fracture probability and Weibull modulus of the fiber in yarn.
