GE Aviation to build unique materials factories | GE Aviation
16/6/2016· One plant of the Huntsville plants will produce silicon carbide (SiC) ceramic fiber. It will be the first such operation in the United States. Today, the only large-scale SiC ceramic fiber factory in the world is operated by NGS Advanced Fibers in Japan, which is a joint company of Nippon Carbon, GE, and Safran of France.
Ceramic matrix composites (CMC), based on reinforcements of carbon fibers and matrices of silicon carbide (called C/SiC or C/C-SiC composites) represent a relatively new class of structural materials. In the last few years new manufacturing processes and materials have been developed. Short fiber reinforcements, cheap polymer precursors and liquid phase processes reduced the costs by almost
