Abstract: A process of compression molding an article from a curable resin is provided that includes opening a mold to an open position by displacing an upper die having an upper mold surface from a lower die having a lower mold surface. Resin is placed a mold surface and the dies are closed to an intermediate start position at a rate of from 1 to 10 cm/sec. The dies are then closed to a start position at a rate of between 25 and 60% of the rate of closure to the intermediate position. A shroud volume is evacuated for at least 3 seconds to a reduced pressure of less than 0.16 atmospheres while continuing to press toward a mold cavity volume at a rate of between 12 and 30% of the rate of closure to the intermediate start. The reduced pressure is removed as the full compression is applied.

Abstract: A vehicle front end load bearing bolster is provided with improved structural performance and a lower component weight, while also minimizing material, tooling, and production costs. The front end assembly is formed with a hydro-formed cross car reinforcement tube secured or bonded with mechanical fasteners and room temperature adhesive to a bolster, thereby improving stress distribution and increasing cross car system stiffness. The bonded hydro-form tube/bolster assembly provides increased torsion stiffness and dimensional stability to the vehicle frame. The hydro-formed cross car reinforcement tube have flattened terminal ends with apertures for integrated attachment to a bolster. The hydro-formed cross car reinforcement tube is formed of aluminum, brass, carbon, steel, stainless steel, copper and high strength alloys. The bolster is formed of high strength plastics and composites including sheet molding compounds (SMC), bulk molding compounds (BMC), and thermoplastic compounds such as glass mat thermoplastic (GMT) and direct long fiber thermoplastic (DLFT).

Abstract: A preform for thermoset resin composition molding is provided that upon cure forms a variety of molded and fiber reinforced articles used in a variety of applications such as vehicle components including bed lines, body components, trim, interior components, and undercar components; architectural components such as trim and doors, marine components including hulls, trim, and cockpit pieces; and similar structures in aerospace settings. A novel slurry composition, a novel centrifugal process, or a combination thereof provide superior quality preforms that are created with greater throughput relative to conventional techniques. The inhibition of fiber movement between the time such a fiber contacts the mold, or fibers already in place on the mold, and the time the fibers are set in position provides a superior fiber homogeneity and randomized orientation relative to existing slurry techniques with attributes of low scrap generation, and process flexibility with respect to part shape and fiber material.
