GE Aviation Building U.S. Blueprint to Industrialize CMCs

$200 million Huntsville operation to produce up to 20 metric tons of material a year

EVENDALE, Ohio--()--The amount of CMC raw material used for GE Aviation will be approximately 20 times greater this year than it was in 2007.

To get there, the business is building the blueprint to CMC industrialization.

GE Aviation is on the final phase to create its most vertically integrated, new material system ever introduced in the United States.

By 2020, GE Aviation is projected to have more than 750 U.S. employees dedicated to its CMC industry.

In just 10 years, GE Aviation has spent more than $1.5 billion to bring advanced CMC technology to market. Beyond GE’s Global Research Center in Niskayuna (NY), this investment includes four production facilities:

  • A CMC laboratory at its headquarters in Evendale (OH) to develop CMC production designs
  • A low-rate production facility in Newark (DE) for CMC raw material and components
  • A full-rate production facility in Asheville (NC) to mass-produce CMCs, including the static turbine shrouds flying in CFM LEAP engines
  • Now, GE Aviation is constructing the last significant piece of the CMCs industrialization puzzle – a full-rate production raw material facility in Huntsville (AL).

Once fully operational, Huntsville will produce up to 20 metric tons (20,000 KG) of CMC material a year. One CFM LEAP engine uses approximately 1 KG of CMC material.

GE Aviation is investing more than $200 million to construct two factories on 100 acres in Huntsville. One plant will mass produce silicon carbide (SiC) ceramic fiber, the first high volume production operation in the United States. Supported by funding ($21.9 million) from the U.S. Air Force Research Lab Title III Office, this plant will dramatically increase U.S. capability to produce SiC ceramic fiber capable of withstanding temperatures of 2400F.

The adjacent GE factory on the same campus will use the SiC ceramic fiber to make unidirectional CMC prepreg necessary to fabricate the CMC components.

“We continue to make great progress,” Huntsville site leader Jon Lyford said. “The engineering and construction teams are on track to start placing process equipment by October. The CMC prepreg facility commissioning will be complete in the summer of 2018. The CMC fiber facility commissioning remains targeted for the spring of 2019.”

The GE Aviation Huntsville team is 24 employees but growing rapidly. Once fully operational, the Huntsville facilities will employ up to 300 people.

The only other large-scale SiC ceramic fiber factory is operated by NGS Advanced Fibers Co. in Toyama, Japan. Formed in 2012, NGS is a joint company of Nippon Carbon, GE and Safran of France. The US SiC fiber plant will license fiber-producing technology from NGS Advanced Fibers Co.

NGS is in the final qualification phase of their expanded factory to increase capacity to meet growing worldwide demand. The SiC fiber plant in Huntsville will complement the growing capacity at NGS.

Advanced Silicon Carbide Fiber, a GE Aviation JV, will sell fiber manufactured in Huntsville to the Department of Defense, GE businesses, Safran and other external customers. The NGS partners will have the opportunity to become equity partners in the Huntsville plant.
