The effect of processing on strength of Nicalon fibers in Nicalon fiber-SiC matrix composites

OSTI ID:5931074
Degradation of strength of Nicalon (silicon carbide) fibers during processing of Nicalon fiber-SiC matrix composites was studied. Strength distribution of as-fabricated Nicalon fibers was obtained via bundle tests. Whereas, strengths of fractured fibers in Nicalon fiber-reinforced SiC matrix composite specimens were estimated by measuring fracture mirror radii. Comparison of fracture probability plots indicate significant differences in the behavior of the as-fabricated fibers and those in the composite. Possible causes leading to these differences are discussed.
