Strength degradation of Nicalon silicon carbide (SiC) fibers during processing of Nicalon fiber-SiC matrix composites was studied. Strength distribution of as-fabricated Nicalon fibers was obtained from bundle tests, whereas the strength of fractured fibers in Nicalon fiber-reinforced SiC matrix composite specimens were estimated by measuring fracture mirror radii. Comparison of fracture probability plots indicates reduction in average strength of as-fabricated fibers after incorporation into composites. Strength degradation of fibers is attributed to thermal degradation and mechanical damage to the fibers during processing.
