    Abstract: A stiffening element comprises a tension and compression member, a shear member, an attachment member, and a plurality of beads. The tension and compression member is positioned spaced apart from the skin and configured to bear tension or compression forces that stiffen the skin and prevent the skin from buckling or bending. The shear member is connected to the tension and compression member and configured to bear shear forces between the skin and the tension and compression member. The attachment member is connected to the shear member and is configured to connect to the skin. The beads each create out-of-plane feature that is positioned in at least one of the shear member and the attachment member. The beads permit the stiffening element be reshaped to adjust a longitudinal curvature of the stiffening element.

    Abstract: A method produces a reinforcing fiber sheet in which a plurality of bundles of reinforcing fibers lined up into one direction to form a plane are adhered to one another through a binder in an amount far smaller than that of the bundles. This method includes step (a) of placing a plurality of reinforcing fibers each having any length at any position on a flat plate, and fixing the reinforcing fibers onto the flat plate, step (b) of placing a binder onto the reinforcing fibers to be adhered onto the fibers, and step (c) of separating the reinforcing fibers from the flat plate.

    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.
