Sic Fibers And Sic/Sic Ceramic Matrix Minicomposites Damage Behavior, Amjad Almansour

Advanced Ceramic Matrix Composites: Science and Technology of Materials, Design, Applications, Performance and Integration

Silicon Carbide based Ceramic Matrix Composites (CMCs) are attractive materials for use in high-temperature applications in the aerospace industry. The performance and durability of a CMC depends on the properties of its constituents. Therefore, the limitations and damage mechanisms of CMC matrix and fiber reinforcement are discussed and characterized in representative simulated application conditions, and the dominant damage mechanisms at elevated temperatures are identified. The tensile creep behavior of single Hi-Nicalon^TM Type S and Sylramic^TM SiC fibers was characterized via testing and creep parameters were extracted. Fiber creep tests were performed in air or vacuum at 1200-1482°C under …
