    Abstract: A three dimensional woven preform, a fiber reinforced composite incorporating the preform, and methods of making thereof are disclosed. The woven preform includes one or more layers of a warp steered fabric. A portion of the warp steered fabric is compressed into a mold to form an upstanding leg. The preform includes the upstanding leg and a joggle in a body portion. The body portion and upstanding leg are integrally woven so there is continuous fiber across the preform. A portion of the warp steered fabric includes stretch broken carbon fibers in the warp direction, and another portion includes conventional carbon fibers. The warp steered fabric can be woven on a loom equipped with a differential take-up mechanism. The warp steered fabric can be a single or multilayer fabric.

  • Publication number: 20150127103
    Abstract: The invention relates to an implantable prosthetic device, a patch, for the repair of connective tissue in an animal or a human. In one embodiment, a biocompatible repair patch (10) for repair of human or animal tissue is disclosed which comprises a tensile load-bearing component in the form of a pre-formed array (13) of a looped configuration in a desired pattern and having at least one return end, said array being formed of an elongate filamentary material; and a base layer (11) of non-woven fibrous material. The pre-formed array is attached to one surface of the base layer so that the pre-formed array retains its configuration while being handled during surgery. The at least one return end serves to receive a suture or the like to attach the patch to tissue. The fibres of the base layer are entangled with the looped configuration so as to attach the array to the base layer and substantially to maintain the desired pattern.

  • Publication number: 20150111449
    Abstract: We report a method of preparation of highly elastic graphene oxide films, and their transformation into graphene oxide fibers and electrically conductive graphene fibers by spinning. Methods typically include: 1) oxidation of graphite to graphene oxide, 2) preparation of graphene oxide slurry with high solid contents and residues of sulfuric acid impurities. 3) preparation of large area films by bar-coating or dropcasting the graphene oxide dispersion and drying at low temperature. 4) spinning the graphene oxide film into a fiber, and 5) thermal or chemical reduction of the graphene oxide fiber into an electrically conductive graphene fiber. The resulting films and fiber have excellent mechanical properties, improved morphology as compared with current graphene oxide fibers, high electrical conductivity upon thermal reduction, and improved field emission properties.

  • Publication number: 20150112434
    Abstract: Absorbable implants for breast surgery that conform to the breast parenchyma and surrounding chest wall have been developed. These implants support newly lifted breast parenchyma, and/or a breast implant. The implants have mechanical properties sufficient to support a reconstructed breast, and allow the in-growth of tissue into the implant as it degrades. The implants have a strength retention profile allowing the support of the breast to be transitioned from the implant to regenerated host tissue, without significant loss of support. Three-dimensional implants for use in minimally invasive mastopexy/breast reconstruction procedures are also described, that confer shape to a patient's breast. These implants are self-reinforced, can be temporarily deformed, implanted in a suitably dissected tissue plane, and resume their preformed three-dimensional shape. The implants are preferably made from poly-4-hydroxybutyrate (P4HB) and copolymers thereof.
