"The CMC components, primarily used for turbine seal segments, are lighter and more tolerant of high temperatures. Made from a continuous silicon carbide fiber reinforcement with a fiber-matrix interface coating surrounded by a ceramic matrix primarily of silicon carbide, the CMCs and other high temperature features were previously evaluated in the HT3 (High Temperature Turbine Technology) demonstrator based on a Trent XWB-97."

No mention of the Thrust Wobbler, though.
