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.
