BEIJING — China is working on a ceramic matrix composite (CMC) but lacks practical applications of such material, says a leading Chinese researcher in the field. More than 4,000 CMC articles have been made for 360 types of parts in China, the researcher told attendees at the China Aeronautical Materials and Manufacturing Equipment Summit, organized by Galleon, in Beijing. Apart from work on parts for turbine engines, Chinese engineers have been applying CMC to ramjets and telemetry systems.

CMC is a key technology, because the material remains stable amid temperatures that defeat even the best metals used in aircraft engines.
BEIJING — China, now making a limited volume of high-grade carbon fiber that it cannot buy from Western countries or Japan, plans to build a plant with 20 times as much capacity. The cost of the fiber, of T800 grade, will be 1,600 yuan ($262) per kg, compared with the 4,200 yuan per kg cost of the established Chinese product, T300, the new plant operator told a conference in Beijing, although it was unclear whether the operator was referring to output from its present facilities.
