Abstract: A system for debundling fiber tow into chopped fibers is provided that has one or more reels of fiber tow, a cutting element configured to receive the fiber tow to form chopped fiber, and a tube with introduced gas flow configured to receive the chopped fiber. A moving belt is positioned under the tube to collect the chopped fiber. A dispenser is positioned along the moving belt for applying a binder or additive. A treatment chamber receives the treated chopped fiber. A process for debundling fiber tow into chopped fibers is provided that supplies one or more reels of fiber tow to a cutting system, drops the chopped fiber into a tube with introduced gas flow to debundle the chopped fiber with a vortex, collects the chopped fiber exiting the tube onto a moving belt, chemically treats the chopped fiber, and provides the chemically treated chopped to a treatment chamber.

Abstract: A monomer is provided for a thermoset molding compound. The monomer is also polymerized with conventional monomers to form thermoplastic polymers. Graphene oxide is used to chelate metal ions to form a graphene oxide chelate that is coupled to a monomer retaining an aliphatic unsaturation capable of free radical polymerization reaction. Inclusion of a metal ion chelated to the graphene oxide affords control over the conductivity of the resultant article. In some embodiments, the monomer is found polymerized into a resulting article proximal to the article surface.
