Conventional Carbon Fiber Conversion-Small, Medium, and Pre-production Scale

National Laboratory: 
Oak Ridge National Laboratory
Processing/Manufacturing Class: 
Fabrication and synthesis
Shaping and forming
Thermo-mechanical processing

ORNL operates three scales of carbon fiber conversion lines at three different locations in and around the ORNL campus. These facilities can convert conventional and non-conventional precursors to carbon fiber and develop new innovative conversion technologies for either increasing the properties of finished carbon fiber or decreasing the cost of producing carbon fiber. The three conversion systems are designed for developing new technologies at small, laboratory scale all the way to providing development quantities of fiber.

Capability Bounds: 

Fiber tows can be processed from as few as 20 to as many as 1,200,000 filaments. Fiber production capacity ranges from 0.1 to 25,000,000 lbs. Temperatures range from ambient conditions to as high as 3500°C, and fiber stretch capabilities are virtually unlimited.

Unique Aspects: 

These carbon fiber lines represent the only carbon fiber development facilities in the world with the capability to scale from small development quantities to several tons that are open to industry. ORNL maintains an expert research staff to complement these facilities with experience in carbon fiber conversion.


These facilities are available for various partnership arrangements with industry.
