Abstract: This invention provides a method of producing a highly electrically conductive sheet molding compound (SMC) composition and a fuel cell flow field plate or bipolar plate made from such a composition. The plate exhibits a conductivity typically greater than 100 S/cm and more typically greater than 200 S/cm. In one preferred embodiment, the method comprises: (a) providing a continuous sheet of a substrate material (bottom sheet) and a continuous sheet of flexible graphite (top sheet) from respective rollers; (b) feeding a resin mixture (comprising a thermoset resin and a conductive filler) to a space between the top sheet and the bottom sheet in such a way that the resin mixture forms a uniform core layer sandwiched between the two sheets to obtain a laminated structure; (c) compressing the laminated structure to obtain a SMC composition having two opposite outer surfaces; and (e) impressing a fluid flow channel to either or both of the outer surfaces (e.g.

Abstract: Disclosed are a nano-composite composition and a method of making such a composite that is composed of a matrix material and dispersed reinforcement nano-scaled graphene plates (NGPs) that are substantially aligned along at least one specified direction or axis. The method comprises: (a) providing a mixture of nano-scaled graphene plates (NGPs) and a matrix material in a fluent state; (b) extruding the mixture to form a filament wherein NGPs are aligned along a filament axis; (c) aligning a plurality of segments of the filament in a first direction, or moving the filament back and forth along a first direction and its opposite direction, to form a NGP-matrix filament preform; and (d) consolidating the preform to form the nanocomposite material. Also disclosed is a method of making a nano-composite fiber.
