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 polyurea additive is provided that strengthens a given base sheet molding composition (SMC) An isocyanate containing species and an amine containing species are introduced into an uncured polymeric resin of a sheet molding compound (SMC) under conditions suitable for the formation of a polyurea polymer network. Upon cure of the SMC base resin, an interpenetrating network is formed that is stronger than the base SMC absent the polyurea. As a result, an article is formed from the SMC that is stronger at the same dimensions than a conventional article or thinned to achieve the same properties to obtain a lightweight article compared to that formed from conventional SMC. The properties of the article are also attractive relative to aluminum for the formation of vehicle body and exterior panels.
