Precursor Structure-Fiber Property Relationships in Polyacrylonitrile Based Carbon Fibers.
Abstract
A complete facility has been designed and constructed to prepare carbon fiber under carefully controlled conditions from selected monomer and polymers. The facility includes laboratory polymerization equipment for preparing and characterizing acrylonitrile copolymers; a spinning dope preparation unit for preparing polymer solutions for extrusion; fiber wet-spinning equipment for conversion of polymer to fiber form; two linear ovens for programmed heat treatment of fiber to produce a stabilized yarn; and two high temperature furnaces for conversion of stabilized fiber to carbon fiber. All processing steps can be carried out under carefully controlled conditions of time, temperature and tension. All units of the facility have been tested and several minor problems have been identified and corrected. All components are now fully operational.
