  • Publication number: 20120312631
    Abstract: The invention is directed at methods, materials, and articles for sound mitigation. The article for sound mitigation is a multi-layered composite article comprising a reinforcing substrate layer and a foam layer. The reinforcing substrate layer includes a fiber phase and a polymer phase. The fiber phase preferably includes one or more natural fibers. The natural fibers may be present at a concentration of about 60 wt. % or more, based on the total weight of the reinforcing substrate layer. The polymer phase is preferably a continuous phase and preferably has a glass transition temperature sufficiently high so that the panel maintains its stiffness at elevated temperatures. The concentration of the polymer phase may be about 10 wt. % or more, based on the total weight of the reinforcing substrate layer. Preferably both the foam layer and the reinforcing substrate layer are effective in reducing the transmission of a sound.

  • Patent number: 7320767
    Abstract: A dimensionally more stable mat is made from a less dimensionally stable mat by saturating the mat with a binder and passing and compressing the mat between a pair of squeeze rolls to remove binder from the mat. At least one of the rolls has a series of annular grooves therein spaced apart along the length of the roll and across the width of the mat whereby as the mat is passed between the rolls a first and a second series of longitudinally extending bands are formed in the mat having different average binder concentrations. The second series of bands, formed in the mat at the annular grooves of the roll, has an average binder concentration greater than that of the first series of bands.

  • Patent number: 7293358
    Abstract: Core sand elements are rapidly and reliably retained in an assembly by driving one or more smooth surface fasteners, such as staples, nails or brads, into the core elements. Such an assembly method comprises positioning at least two core elements in a core assembly, positioning a smooth surface fastener for entry into the at least two core elements, and driving the smooth surface fastener into the two core elements to fasten them in the core assembly. In such a preferred method, the smooth surface fastener comprises a staple with two smooth surface tines connected by a crown and the staple is positioned for entry of one tine into each of two core elements with the crown of the staple spanning the interface between the two core elements.

  • Patent number: 7186361
    Abstract: In a continuous molding apparatus equipped with a long core 10 having a curvature disposed on a plane, a release film supplied from a lower release film feeder 20 is sent onto the core 10, and prepreg sheets supplied from a prepreg sheet feeder 30 are laminated thereon and preformed. A release film supplied from a release film feeder 40 is disposed on top of the laminated body, before the body is sent into a hot press 50. A puller 60 moves the laminated body without loading tension thereto. The laminated body enters a postcure device 70 in which thermosetting of the material is completed.

  • Patent number: 7090795
    Abstract: A method for making figures/stripes on an article, including steps of: preparing a substrate; wrapping an outer surface of the substrate with a fiberglass fabric drenched with resin; placing at least one thin or slender covering material on an outer face of the fiberglass fabric, the substrate, fiberglass fabric and the covering material together forming a wrapping body; using a binding means to bind the wrapping body to harden and pattern the fiberglass fabric; taking off the binding means after the wrapping body is hardened and patterned, whereby the fiberglass fabric is hardened to form an inner layer, the covering material positioned on the inner layer and forming the figures/strips; painting an outer resin on an outer face of the wrapping body after the outer resin is hardened; and buffing the hardening layer to complete the article.

  • Patent number: 7081219
    Abstract: A method for manufacturing a molded structure in a press that includes a first mold and a second mold is provided. The second mold has a plurality of pressure actuators, with each pressure actuator capable of independent operation. The method includes the steps of positioning a preform having a thickness in the first mold, placing a quantity of resin adjacent the preform so as to create a resin reservoir, and then selectively actuating one or more of the pressure actuators apply pressure to the resin reservoir to force at least a portion of the resin reservoir to infuse through the thickness of the preform. The method may also include curing the resin-infused preform, and then removing the cured resin-infused preform from the first mold.

  • Patent number: 7056976
    Abstract: Polyisocyanate-based reaction systems, a pultrusion process of those systems to produce reinforced matrix composites, and to composites produced thereby. The polyisocyanate-based systems are mixing activated reaction systems that include a polyol composition, an optional chain extender or crosslinker, and a polyisocyanate. The polyisocyanate-based systems exhibit improved processing characteristics in the manufacture of fiber reinforced thermoset composites via reactive pultrusion.
