  • Publication number: 20130337256
    Abstract: In a method of manufacturing an object, a filament is fed to an extrusion head. The filament has a semi-crystalline polymeric reinforcement portion and a polymeric matrix portion. The temperature of the filament is raised in the extrusion head above the melting point of the matrix portion but below the melting point of the reinforcement portion so that the matrix portion of the filament melts within the extrusion head, thereby forming a partially molten filament within the extrusion head. The reinforcement portion of the partially molten filament remains in a semi-crystalline state as it is extruded from the extrusion head. Relative movement is generated between the extrusion head and the substrate as the partially molten filament is extruded onto the substrate in order to form an extruded line on the substrate. The matrix portion of the extruded line solidifies after the extruded line has been formed on the substrate.

    Abstract: A plurality of reversible active composite materials are disclosed, including composites based on a shape memory alloy member (SMA) and a shape memory polymer member (SMP), as well as composites based on two different SMP members. Each different member (SMA or SMP) will be trained to remember a specific shape at a specific temperature. Where two different SMP members are employed, the members exhibit different glass transition temperatures. Such composite materials can be implemented in many form factors, including two generally planar members, a single generally planar SMP member with SMA fibers distributed throughout the SMP, and a SMA fiber/wire coated with a SMP coating. In particular, the SMA fiber/wire coated with a SMP layer can be used to form helical coils that can be used in paired hinges to achieve reversible bending of a structure into which such paired hinges are incorporated.

    Abstract: Fibers are spun from a supported array of nanotubes. Fibers are spun using a spinning shaft with, for example, a hook shaped end that contacts the supported nanotubes and twists some of them around each other to begin the fiber. As the twisted nanotubes detach from the support, the shaft moves away from and along the supported array in a controlled direction and at a controlled speed as it spins to twist and detach additional nanotubes from the support and extend the length of the fiber. If the array is pretreated with a dilute polymer solution, excess solution is squeezed out of the growing fiber during spinning, and the polymer may be cured at elevated temperature to provide a strong nanotube composite fiber.

    Abstract: A primer/topcoat coil coating system employs crosslinkable branched hydroxyl-functional polyester-imide resins derived or derivable from a symmetric aromatic imide trial and a diacid or acid-producing derivative. The primer resin has a hydroxyl number greater than about 90 but not more than about 215, the topcoat resin has a hydroxyl number greater than about 100 but not more than about 215, and the primer and topcoat can each be hardened in 30 seconds or less to provide a coating having at least 0T flexibility with no tape off and at least 2H pencil hardness.

  • Publication number: 20100112282
    Abstract: A fiber includes a base having a surface to be impacted by a fluid wave for propelling the fiber forward and a body having a trailing end connected to the base, a leading free end, and a spiral shape causing the fluid wave to rotate the fiber. A locking system causes the fiber to engage and hold at least one other fiber being propelled and rotated by the fluid wave.

  • Patent number: 7687009
    Abstract: A fiber includes a base having a surface to be impacted by a fluid wave for propelling the fiber forward and a body having a trailing end connected to the base, a leading free end, and a spiral shape causing the fluid wave to rotate the fiber. A locking system causes the fiber to engage and hold at least one other fiber being propelled and rotated by the fluid wave. A process for producing three-dimensional, self-interlacing composites by mechanical polymerization with ultrasonic manipulation, includes placing the fibers and a mixing fluid in a form or mold. The fluid is subjected to ultrasonic manipulation in a mixing step, causing the fibers to be propelled, rotated and three-dimensionally engaged and held to one another.

  • Publication number: 20100062207
    Abstract: A shag rug and method of making the same using smooth bamboo yarns formed in chenille pile. The smooth bamboo yarns have a low coefficient of friction and thus the rug and method utilize a blend of bamboo and combed cotton. The blended yarns are formed into chenille and shag of a dense woven character with a subtle sheen. To augment the bamboo yarns, blends of other fibers provide a cotton canvas base for the rug and a backing cloth beneath the base along with a polypropylene border. The blends of fibers vary according to the intended use and location of the shag rug. The shag rug of bamboo resists damage from water, mold, and mildew while limiting the retention of allergens in the bamboo fibers. The bamboo shag rug can be readily cleaned and dried.

  • Publication number: 20080047734
    Abstract: A cable includes a cable sheath in which are embedded a plurality of insulated conductors at least two of which are helically twisted, the cable being provided with visible markings that indicate where one can electrically engage a selected one of the conductors by an insulation-piercing contact. The cable is formed by arranging a plurality of insulated conductors in a light-transmitting synthetic plastic sheath layer, two or more of the insulated conductors being helically twisted about a longitudinal axis, which cable is optically scanned to determine locations at which contiguous portions of the twisted insulated conductors are superposed orthogonally relative to a reference plane, whereupon markings are formed on the cable sheath layer at locations laterally spaced from the contiguous conductor portions, whereby a selected one of the twisted conductors may be engaged by an insulation-piercing contact.

  • Patent number: 7229688
    Abstract: A self-texturing hollow fiber that exhibits a desirable tendency to coil rather than to bend sharply or zig-zag. In one embodiment the invention is a hollow polymer filament having a generally cylindrical cross-section. The filament is further defined by a cylindrical wall formed of at least two generally C-shaped sections, each section including first and second ends separated by an intermediate portion in which no two points along the cross-section of the wall corresponding to the intermediate portion share the same width. In another aspect, the invention is a coiled bilateral hollow polymeric filament in which the two component polymers are identical except for their degree of orientation. The filament is further defined by a non-linear wall formed of at least two non-linear sections.
