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 translation: 提供了一种将碳纤维丝束分解成适用于模塑组合物配方的分散短切碳纤维的方法。 碳纤维丝束被供给到具有流体流动开口的模具中，流体通过该模具撞击在丝束的侧面上以使丝束横截面积膨胀。 膨胀的横截面积纤维束从模具延伸到常规纤维切碎装置的路径中以形成切碎的碳纤维，或通过接触机械剥离器的齿。 通过调节流体流动开口相对于纤维束通过的模孔的相对位置，实现了冲击在丝束上的流体的性质，孔的形状，其组合，改进了切碎的碳纤维分散体。 得到的切碎的碳纤维可以在制剂固化之前分散在模塑组合物制剂中。

Abstract: A vehicle component is provided that includes a first cured layer of a molding composition having a predominant fiber filler chopped glass fibers, a second cured layer of molding composition having a predominant fiber filler chopped carbon fibers, and an elastomeric bonding agent with elongation properties configured to accommodate the differential coefficients of linear thermal expansion between the first cured layer and the second cured layer. The second cured layer is substantially devoid of glass fiber. The bonding agent is an elastomeric adhesive, which is operative from −40 to 205° C. The first cured layer forms an outer skin layer surface of a vehicle and the second cured layer forms an interior layer, where the outer skin layer surface has a class-A finish.

Abstract: A process and system are provided for introducing a blend of chopped and dispersed fibers on an automated production line amenable for inclusion in molding compositions as a blended fiber mat for structural applications. The blend of fibers are simultaneously supplied to an automated cutting machine illustratively including a rotary blade chopper disposed above a vortex supporting chamber. The blend of chopped fibers and binder form a chopped mat. The chopped mat has a veil mat placed on either side, and is consolidated with the veil mat using heated rollers maintained at the softening temperature of thermoplastic binder, with consolidated mats being amenable to being stored in rolls or as flat sheets. A charge pattern is made using the consolidated mat, and the charge pattern can be compression molded in a mold maintained at a temperature lower than the melting point of the thermoplastic fibers.

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 molding composition formulation is provided that includes polypropylene, glass fiber, and a polypropylene substitute including recycled sheet molding composition transfer film. The polypropylene substitute is present from 1 to 35 total weight percent also may include natural cellulosic fibers or powders. A process is provided by which the polypropylene substitute is mixed and homogenized and then mixed with polypropylene and additives, and thereafter glass fiber. A reduction in the amount of virgin polypropylene used is reduced compared to conventional thermoplastic glass fiber filled moldings.
