Ceramics in the skies!

In this issue we look at how ceramics—particularly ceramic matrix composites—will aid in the development of next-generation aircraft. Four feature articles discuss ceramics used within jet engines, “super” turbines, and environmental barrier coatings, and how advanced materials are playing a role in solving key technical challenges to realizing commercial electrified aircraft.

Also, learn a few basic aircraft statistics from an infographic created just for this issue, and see the latest news for three upcoming spring and summer meetings—ICG, GMFAT-2/Bio-4, and EHS.

In addition to industry, many grad students are also pursuing research on ceramics for aircraft. Learn about one student's research in this month's Deciphering column, in which University of Virginia Ph.D. candidate Lavina Backman describes her research on ultra-high temperature oxidation of high entropy ultra-high temperature ceramics (UHTCs).

Finally, make sure to take a look at what to expect in Cleveland this year at Ceramics Expo 2019, which will feature a new two-day format.

Feature Articles

 

Ceramic matrix composites taking flight at GE aviation


Jim Steibel
The holy grail for jet engines is efficiency, and the improved high-temperature capability of CMC systems is giving General Electric a great advantage.

Nonoxide polymer-derived CMCs for "super" turbines


Zhongkan Ren and Gurpreet Singh
The melting point of single-crystal blades limits further advancement in operating temperature of gas turbines with metallic materials. Ceramics, which have much higher melting points, hold the promise for future "super" turbines.

Taking off: Advanced materials contribute to the evolution of electrified aircraft


Ajay Misra
Commercial electrified aircraft are expected to take off within the next decade—and advanced materials are playing an increasingly critical role in solving key technical challenges that will push the boundaries even higher.

Environmental barrier coatings enhance performance of SiC/SiC ceramic matrix composites


Kang N. Lee and Mark van Roode
Environmental barrier coatings protect the structural integrity and mechanical strength of ceramic matrix composites, allowing these revolutionary materials to boost gas turbine engine efficiency.
