  • Publication number: 20250215619
    Abstract: The invention is directed to carbon fibers prepared from polyacrylonitrile (PAN) dopes aged at low temperatures. The PAN dopes are aged at low temperatures to facilitate the formation of certain structures in the PAN polymer. When the PAN comprising these structures is formed into carbon fibers, these fibers have improved tensile properties. Alternative methods of introducing the certain structures into PAN fibers are also provided for by the invention.

  • Publication number: 20240150958
    Abstract: Provided are sizing compositions, and more particularly, sizing compositions comprising an epoxy and a carboxylate salt of an amine compound for the treatment of carbon fiber. The structure of the amine used to make the carboxylate salts is RnXmQ, wherein Q is an amine-containing group, X is a polyether group, and R is an aryl or alkyl group, either linear or branched, saturated or unsaturated, or a combination thereof. m and n are integers greater than or equal to 0. The compositions reduce or eliminate sheen and luster on carbon fibers in finished goods. Carbon fiber-reinforced composite materials and carbon fibers incorporating said sizing compositions are also provided.

  • Publication number: 20180023244
    Abstract: A composite carbon fiber having a carbon fiber to which an amine-functionalized polymer is electro-grafted onto a surface thereof is provided. Electro-grafting the amine-functionalized polymer onto the surface of the carbon fiber results in a composite carbon fiber in which the polymer is covalently bonded to the fiber, and in which a significant number of reactive amine groups are available for subsequent reactions, such as for reacting with a resin matrix in the production of a fiber reinforced composite. As a result, the composite carbon fibers may be particularly useful in producing fibers reinforced composites that exhibit improved interlaminar strength. Fiber reinforced composites are also provided.
