ORNL makes low-cost carbon fiber available to American manufacturers

The DOE's Carbon Fiber Technology Facility, operated by ORNL, is accepting proposals from companies that want to test low-cost carbon fibers manufactured at the pilot-scale plant. Here, textile-grade acrylic fibers enter the first of four oxidation ovens, where they gradually turn from white to brown to black. Once fully oxidized, high-temp furnaces convert the material to carbon fiber.

 

 

 

 

Companies interested in testing the latest in low-cost carbon fiber have a new opportunity to partner with the Department of Energy's Carbon Fiber Technology Facility in Oak Ridge, Tenn.

The CFTF, operated by Oak Ridge National Laboratory (ORNL) as part of the Department's Clean Energy Manufacturing Initiative, opened earlier this year to find ways to reduce carbon fiber production costs and to work with the private sector to stimulate widespread use of the strong, lightweight material.

In its first months of operation, the CFTF used traditional raw materials to assure the new pilot-scale manufacturing line would produce a commercial-quality product. With that goal accomplished, the facility now will use less expensive "precursor" materials that can be turned into carbon fiber more cost effectively.

"The first alternative precursors we are working with are lower-cost, textile-grade acrylic fibers that we will turn into sample lots of carbon fibers," says CFTF Director Lee McGetrick. "Companies that would like to obtain some of this material for prototyping of composite applications are invited to come and talk to us."

ORNL is accepting proposals from companies that want to try out the low-cost carbon fiber to develop new products and tap markets in such areas as transportation, energy production, and infrastructure. The full federal business opportunity announcement is available here.

The 42,000-sq-ft CFTF has the flexibility to try out different kinds of precursor materials, which typically comprise about half of carbon fiber production costs. In addition to the textile acrylic fiber now in use, CFTF researchers are experimenting with other inexpensive alternatives such as lignin, a byproduct of biorefineries and the pulp industry.

"We're uniting ORNL's unique facilities, scientific, and engineering expertise with industrial partners to stimulate broader application of carbon fiber to create new products that will result in the revitalization of American manufacturing," says Craig Blue, who directs ORNL's advanced manufacturing program and the Manufacturing Demonstration Facility (MDF).

The CFTF draws on ORNL's broad portfolio of manufacturing and materials science expertise and is closely integrated with the lab's MDF, which offers additional equipment and resources in advanced manufacturing. Companies that would like to work with the MDF in the areas of additive manufacturing or carbon fiber and composites are invited to submit collaborative project proposals; details can be found here.

The CFTF is supported by DOE's Energy Efficiency and Renewable Energy Office through the Advanced Manufacturing and Vehicle Technology Offices. Industrial collaborators must provide in-kind contributions to partner with the CFTF. More information about the CFTF and carbon fiber research at ORNL can be found here.

ORNL is managed by UT-Battelle for the Department of Energy's Office of Science. For more information, go to http://science.energy.gov.
