摘要： 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.

摘要： A method for forming an elevated surface feature for compression molded assemblies includes the placement of an afore-mentioned insert onto an actuated fixture pin with the pin initially in a retracted position. An upper portion of a mold configured with said retracted actuated fixture pin over a preform of pre-preg plies placed on the bottom portion of the mold is then closed. The fixture pin is actuated towards the pre-preg plies when a flowable material fills a molding cavity in the upper portion of the mold. The cavity is configured to form the elevated surface feature with the advancing action of the insert packs out the surface feature under the pressure of the pin to eliminate porosity in the elevated surface feature in the molding cavity.

摘要： 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.
