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: Unique methods for the efficient and beneficial use of converting dry nanomaterials such as dry carbon particles into liquid nano-agents are disclosed herein. The methods provide for fabrication of polymer and fiber reinforced composites, such as fiber-reinforced resins having such introduced nanomaterials to enable an increased dispersion and other beneficial properties.
