摘要： A lightweight and simplified vehicle door assembly is provided with four main components, an upper frame positioned about the window, an inner frame structure, an outer body panel, and a composite reinforcement component. The composite reinforcement component provides an all-in-one solution for a side impact cross beam, as well as an upper door reinforcement, a front door pillar reinforcement, and a rear door pillar reinforcement. The composite reinforcement component acts to reinforce the overall door structure, offers resistance to a side impact that limits the intrusion into the passenger compartment, and offers resistance to a frontal impact by maintaining the spacing between the vehicle A and B pillars (for a front door) and pillar C and D for a back door. A coupe vehicle door in which there is no window frame may be reinforced with the composite reinforcement component. The composite reinforcement component may have continuous or chopped fibers.

摘要： A process for resin transfer molding (RTM) with injection and overflowing of a resin through one or more troughs is provided that includes the injection of resin into a plurality of injection ports feeding the one or more troughs and overflowing the resin in into a mold. The temperature and pressure are controlled as applied to the mold. The injection ports are activated for injecting the resin in any order of individually, in groups, or pairings. A resin transfer molding (RTM) system for performing the process includes a mold having a cavity. A set of injection ports feed one or more continuous channels between the cavity and a reservoir of resin. A numerical controller selectively activates the injection ports to overflow the resin into the cavity in any order of individually, in groups, or pairing.

摘要： A composite sandwich panel assembly including an open area core, a high gloss surface sheet, and a structural skin. The open are core defines a plurality of pores and has a first face and an opposing second face. The high gloss surface sheet is adhered to the first face of the open area core by a first adhesive layer. The high gloss surface sheet has a high gloss surface. The structural skin is adhered to the second face of the open area core by a second adhesive layer. A process for forming the composite sandwich panel assembly includes positioning the high gloss surface sheet, joining the first face of the open area core to the high gloss surface sheet with a first adhesive layer intermediate therebetween, and joining the structural skin to the second face of the open area core with a second adhesive layer intermediate therebetween.

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.

摘要： A dual layer cured composite article is provided that has an outer part having an outer part thickness composed of a first resin matrix having between 50 and 70 total weight percent of the outer part being an outer part mixed fiber filler, the outer part mixed fiber filler having an outer part primary fiber:carbon fiber ratio of 0.05-20:1. An inner part complementary to the outer part is provided and has an inner part thickness composed of a second resin matrix having between 40 and 60 total weight percent of the inner part of an inner mixed fiber filler, the inner mixed fiber filler having an inner part primary fiber:carbon fiber ratio of less than said outer part primary fiber:carbon fiber ratio. A joinder between the outer part and the inner part is provided. A process for producing such an article is also provided.

摘要： 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.

摘要： 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.
