Vorrichtung zur Herstellung von Kohlenstoffilamenten

摘要

Apparatus for production of continuous cords or yarns of carbon fibres of high strength and Young's modulus from organic polymers, esp. from polyacrylonitrile. The apparatus comprises a feed spool of organic polymer fibre cord or yarn; a brake for this; oxidation oven contng. devices for keeping oxidising atmosphere and maintaining a temp. of up to 250 deg.C.; supporting and internal driving devices for the fibre, running at predetermined speed, while the fibre is maintained under tension controlling its length. A take-up device receives the oxidised fibres as they leave the oven. The driving and take-up devices maintain sufficient tension on the fibres to prevent them slipping. There is also a carbonisation furnace contng. devices permitting a non-oxidising atmosphere to be maintained, and temp. gradient rising of 1,000 deg.C.; a second feed spool for introducing the oxidised fibres into the carbonisation furnace, and a take-up device for receiving the carbonised fibres as they leave the furnace.
