Advanced ceramic matrix composites (CMCs) are enabling materials for applications in various industries such as energy generation and storage (e.g., concentrated solar power, nuclear, combustion, batteries), extreme environment, space, transportation, medicine, microelectronics, and optical systems. High mechanical and thermal reliability is a key issue for their ultimate use in short- to very long-term applications. Understanding the thermomechanical performance of composites is essential to effectively life-model CMC performance for desired uses and to discern advancements in CMC technology. Effective test techniques which incorporate aspects of stress, time, temperature, and environment are critical for this work which necessitates understanding the effects of material variation, test environment, the statistical nature of the results as well as degradation mechanisms and fracture mechanical behavior. Further advancement of elevated temperature testing which better represents use conditions and/or produces improved diagnostic understanding of material response to thermomechanical environment is highly sought after. Identification and quantification of failure mechanisms by fracture, creep, fatigue, oxidation and/or irreversible deformation are essential, as well as their correlation with structure, processing, and exposure to severe service conditions. Extreme environments and challenging applications have necessitated new approaches for sustainable manufacturing and characterization of CMCs. The development of novel methods to advance and accelerate computationally driven materials characterization and validate structure/property relationship is needed to improve predictions of material behavior and lower costs.
This symposium solicits abstracts related to the diverse aspects of mechanical behavior of CMCs and their constituents, including environmental barrier coatings (EBCs) and correlations with processing, component performance and reliability. Presentations which address these issues, including standards and database development of these properties, are welcome.
