Enhancing Ceramic Matrix Composite (CMC) Temperature Performance in High-Hydrogen Environments using Field Assisted Sintering Technology

The overall objective of this project is to significantly improve the temperature performance by at least 150° C of ceramic matrix composite (CMC) materials in high-hydrogen environments using field assisted sintering technology (FAST). FAST is a relatively new material synthesis technology that allows for novel materials to be processed at significantly shorter fabrication times by using high-density electrical currents to drive rapid, high-intensity heating.The project objective will be achieved by the following methodology. FAST-derived CMCs in conjunction with advanced ceramic coatings will be developed to adapt to higher-temperature combustion with higher-humidity contents as a result of the high-hydrogen fuel. The fabricated samples will be tested at a range of combustor operating conditions with up to 100% hydrogen fuel to understand the impact of different CMC formulations and combustion gas environments on the material performance.
