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.

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.
