  • "SiC CMCs can be used to replace combuster liners, turbine blades, turbine shrouds," Douglas Kiser, ceramic research engineer at NASA's Glenn Research Centre, said.

    "The reason we've been developing the SiC/SiC CMCs is to reduce the weight of the components. In comparison with the nickel-based super alloys the SiC/SiC CMCs have a density of about a third. They can operate at temperatures of around 700 degreesF higher than metallic components and they have reduced cooling requirements," Kiser explained.

    NASA is currently working on the TTT project - transformational tools and technology project - which looks at materials which can be used about 2700 degreesF, "so that the engines can operate at higher temperatures and we can obtain better fuel efficiency".
