  • 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: Composite materials are provided that include nanostructures bound together by a binder material in a manner that provides the composite material with high strain capability and toughness. The nanostructures and binder material form a matrix material in which long fiber reinforcements may be embedded to form a structural composite material. The nanostructures may have relatively low aspect ratios, preventing entanglement during processing. The nanostructures can be arranged in an interconnected network to form a high free-volume skeletal structure within the matrix material that allows the nanostructures to flex and return to their original shapes. As applied to ceramic matrix composite (CMC) materials, this tough, flexible matrix material allows for full bonding of the matrix material with the fiber reinforcements so that CMC materials can realize the full potential of the reinforcing fibers and possess superior inter-laminar strength.

  • Patent number: 8455088
    Abstract: The present disclosure relates to compounds from which nanofibers can be produced, the resulting nanofibers produced from the compounds, and nanofiber reinforced polymers prepared using the nanofibers and a polymer. The compounds used in forming the nanofibers include chemical linkage moieties that are capable of forming non-covalent bonds with portions of the polymer so as to form the nanofiber reinforced polymers. The nanofiber reinforced polymers are useful as biomaterials in medical devices.

  • Publication number: 20130136914
    Abstract: Disclosed is a method for preparing hollow carbon fibers having an empty space in the cross section thereof. More specifically, the disclosed method includes preparing a spinning solution of an acrylonitrile-based polymer having a viscosity ranging from 2000 to 5000 poise at room temperature; spinning the prepared spinning solution using a spinneret designed for spinning hollow fibers; super-drawing and drawing spun fibers to prepare hollow precursor fibers; and stabilizing and carbonizing the hollow precursor fibers to prepare the hollow carbon fibers. The hollow carbon fibers obtained by the disclosed method have a lower specific gravity by 10 to 50% than conventional hollow carbon fibers (solid), but have similar mechanical properties to the conventional fibers. Furthermore, in the method, the diameter of carbon fibers can be adjusted. Thus, it is possible to widen the application of hollow carbon fibers.

  • Publication number: 20130122244
    Abstract: A multifunctional fully integral panel system design, a unique material configuration, and a process for fabricating a net shape (or nearly net shape) panel in one production cycle. The panel may comprise a base facing with an outer perimeter, a decorative film applied to the exterior of the base facing, an aft facing having an outer perimeter fused to the base facing, and a reinforcement core disposed between the unfused portions of the base and aft facings, which reinforcement core also acts as acoustic insulation (i.e., a noise attenuator). Alternatively or additionally, a foam core or blanket having thermal and/or acoustic insulation properties is attached to the external surface of the aft facing. The fabrication process involves the application of different heat treatments to panel components having different forming temperature or rubbery/elastic plateaus.

  • Publication number: 20130115439
    Abstract: A carbon nanotube film includes a first end and a second end. The second end is opposite to the first end. The carbon nanotube film includes a number of carbon nanotube wires and at least one first carbon nanotube film connected adjacent carbon nanotube wires of the number of carbon nanotube wires. The carbon nanotube wires fan out from the first end to the second end such that a distance between the adjacent carbon nanotube wires gradually increases from the first end to the second end. The carbon nanotube film defines an open angle. A method for making the above-mentioned carbon nanotube film is also provided.
