Fiber-reinforced ceramic tubular composites
Ceramic fiber-ceramic matrix tubular composites have been developed in a joint program of Oak Ridge National Laboratory (ORNL) and the Babcock and Wilcox Company. This program was the first collaborative agreement between a private industry and ORNL. The ceramic tubular composites were fabricated using a novel chemical vapor infiltration process developed at ORNL. Silicon carbide filament-wound preforms were infiltrated with additional silicon carbide to form the matrix phase of the composite. The tubular composites exhibited exceptional strength and strain tolerances that were significantly higher than monolithic (nonreinforced) SiC. C-ring strengths and fracture surface evaluation of both room-temperature- and elevated-temperature-tested specimens are presented. 30 refs., 23 figs., 3 tabs.
