Advanced Fibers Manufacturing Group

 

Developing technologies for the manufacturing of fiber and intermediate feedstock

Researchers within the Advanced Fiber Manufacturing Group work with industry to support the demonstration, deployment, and validation of material innovations such as the development of low-cost precursors and energy efficient advanced conversion processes at an industrial-relevant scale. Recent research efforts have enabled domestic sources for advanced fibers and supported a manufacturing workforce development program to enhance industry adoption of new technologies.

The group not only focuses on developing scale-up science and technologies for advanced fiber manufacturing, but also supports the associated fabrication of functional components for energy applications, including compressed gas storage, wind energy, and vehicle lightweighting. In addition, researchers are investigating intermediate and composite production techniques such as compounding, tow-preg, and pultrusion for carbon fiber.  As a strong, stiff, lightweight material, carbon fiber is one example of an advanced fiber that can be used in automobiles, wind energy, oil and gas, and infrastructure. Innovative performance-focused materials and processes can also potentially drive significant performance improvements for national security applications.

In the early months of the Covid-19 pandemic, researchers at ORNL worked with industry and academia to rapidly demonstrate and deploy the production of N-95 mask filter material. These efforts led to the n ongoing mass production of millions of face masks and the creation of thousands of jobs.

Facilities

The Carbon Fiber Technology Facility (CFTF) is the Department of Energy’s only designated user facility for carbon fiber innovation, providing a platform for identifying high potential, low-cost raw materials, including textile, lignin, polymer, and hydrocarbon-based precursors.

The Manufacturing Demonstration Facility (MDF) is dedicated to improving the energy and material efficiency, productivity, and competitiveness of American manufacturers. Research focuses on manufacturing analysis and simulation, composites and polymer systems, metal powder systems, metrology and characterization, machine tooling, large-scale metal systems, and robotics and automation.
