Abstract: A sheet molding compound (SMC) is provided with superior conductivity properties based on the use of graphitics. A process for exfoliation of GnP and turbostratic carbon is also provided. By exfoliating the graphitics, a reduced amount of material can confer comparable properties relative to native GnPs or turbostratic carbon thereby reducing the amount of material usage, but also reducing negative effects to the base resin formulation through inclusion of these additives. Particular utility is found in thermoset resin molding to produce articles that are amenable to electrostatic coating and other surface treatments that rely on surface conductivity and especially in the realm of vehicle body parts.

Abstract: A process for debundling a carbon fiber tow into dispersed chopped carbon fibers suitable for usage in molding composition formulations is provided. A carbon fiber tow is fed into a die having fluid flow openings, through which a fluid impinges upon the side of the tow to expand the tow cross sectional area. The expanded cross sectional area tow extends from the die into the path of a conventional fiber chopping apparatus to form chopped carbon fibers, or through contacting tines of a mechanical debundler. Through adjustment of the relative position of fluid flow openings relative to a die bore through which fiber tow passes, the nature of the fluid impinging on the tow, the shape of the bore, in combinations thereof, an improved chopped carbon fiber dispersion is achieved. The chopped carbon fiber obtained is then available to be dispersed in molding composition formulations prior to formulation cure.

Abstract: A molding composition formulation includes a thermoset cross-linkable 12 to 45 micron polymeric resin. Hollow glass microspheroids are present from 2 to 12 total weight percent. An article formed from such a composition is further strengthened by the addition of a surface activating agent bonded to the surface of the glass microspheroids. Conventional particulate fillers when added to an inventive formulation provide enhanced performance when the filler particle has a size sufficiently small to insert within adjacent microspheroid interstitial voids. An unsaturated polyester resin so formed is particularly well suited for the formation of sheet molding compound formulations.

Abstract: A process of formulating a curable thermoset resin formulation is provided that includes reacting a natural cellulosic filler with at least one of: a silsesquioxane, a isocyanate, a base, or an organic acid to form a reduced hydrophilicity filler. By intermixing the resulting reduced hydrophilicity filler with a thermoset cross linkable polymeric resin, a curable thermoset resin formulation is formed that has superior properties to conventional formulations in terms of density and environmental impact. The formulation properties in terms of strength of the cured article are improved relative to untreated natural fillers. The treatment is advantageous relative to plasma treatment. An article is also provided produced upon cure of the formulation.
