ABSTRACT:
Process of carbon fiber manufacture wherein the polyacrylonitrile precursor is stretched prior to oxidation step of the carbonization operation but after the stretching step of the spinning operation in limited temperature range. Process permits greater throughput in precursor manufacture and reduces flaws in the precursor because significant stretching is at lower line speeds typically used for oxidation and carbonization in making carbon fiber.
