Abstract: The present disclosure relates generally to carbon fibers having high tensile strength and modulus of elasticity, as well as a process for the manufacture of such carbon fiber. The process comprises spinning a polymer/solvent solution into a solvent/water bath in the range of 78%-85% solvent, thereby producing a dense fiber structure, and subsequently carbonizing the polymer precursor fiber at a lower than typical carbonization temperature to form carbon fibers.

Abstract: The present disclosure relates to the control of the degree of swelling of polymer fiber, such as polymer fiber used in the manufacturing of composite materials, by control of the pH of the coagulation bath during spinning.
