Next-generation ceramic matrix composites (CMCs) are being developed for future appliions such as turbine blades (top left).These may use new technologies such as water-like polymers that can be processed into 1700 C-capable, low-density ceramics (bottom) or nanofibers grown onto silicon carbide (SiC) reinforcing fibers for increased toughness (top right).
CMCs consist of silicon carbide ceramic fibers and ceramic resin, enhanced with proprietary coatings. More durable than metal, CMC components contain one-third the density of typical metallic
material systems. However, at present, practical CMC matrices are limited to Al 2 O 3 (aluminum oxide)-based and SiC (silicon carbide)-based materials. Also, in order to prevent damage due to chemical instability or a difference in coefficient of thermal
The continual drive for greater efficiency and power density in power conversion systems is leading to the expanded use of silicon carbide (SiC). This wide-bandgap semiconductor has a dielectric breakdown capability 10 times that of silicon with excellent thermal conductivity.
In contrast, the silicon carbide tape factory is solely a GE endeavor. The facility “will apply proprietary coatings to the ceramic fiber and form them into a matrix to produce CMC tape,” which will be used at GE’s CMC manufacturing facility in Asheville, N.C.
