WebJan 8, 2024 · In addition, the creep parameters of both composites were determined. Results indicate that in 2D woven MI SiC/SiC composites with Sylramic™-iBN or Hi-Nicalon™-S fibers, creep is controlled by chemical vapor infiltration (CVI) SiC matrix, whereas in 2D laminated MI SiC/SiC composites with Hi-Nicalon™-S fibers, creep is …WebEvaluation of CVI SiC/SiC Composites for High Temperature Applications. Establish stress-dependent and temperature-dependent parameters for modeling SiC/SiC composite creep behavior. Assess durability at 2200°F (1200°C) to 2700°F (1482°C) in air while under different mechanical loadings for up to several hundreds of hours.
