    Abstract: A method and apparatus for forming a tubular from a composite material. The composite material includes fibers and epoxy resin that are formed into plies that are wound around an axis to form an annular member. The fibers in each ply are arranged axially and hoopwise. The axially oriented fibers are angled from about 10° up to about 20° with respect to an axis of the tubular. The hoopwise fibers are wound in the plies ranging from about 60° at the innermost ply up to about 90° in the outermost ply. The hoop fibers in the intermediate plies are arranged at increasing angles with distance away from the innermost layer. Transitioning the hoop fiber alignment in the successive plies better distributes hoop stress through the wall of the tubular thereby reducing stress concentrations on the innermost ply.

  • Publication number: 20130304232
    Abstract: A tubular structure and method for making a tubular structure are provided, where the tubular structure includes at least one layer of braided strands. In general, at least one portion of the braided strands exhibits a braid pattern of crests and troughs (e.g., a wave pattern, which may include sinusoidal, square, and/or sawtooth waves) along a length of the tubular structure. The wave pattern can be created by rotating the mandrel onto which the tubular structure is braided during the braiding process, such as by angularly oscillating the mandrel about its longitudinal axis or about its transverse axis. As a result, the tubular structures may have increased radial strength, collapse resistance, torque transmission, column strength, and kink resistance. The tubular structures may be used in medical devices, such as stent-grafts, as well as in other medical and non-medical devices, such as in hoses, tubing, filters, and other devices.

  • Patent number: 8541090
    Abstract: A method is presented for making a composite material from strips comprising longitudinal fibers and a binder or resin, which material comprises a number of layer assemblies one on top of the other. Each layer assembly comprises m sets (with m at least 2) of parallel strips each extending in a different direction, Each layer assembly is manufactured by successive steps of depositing groups of parallel strips according to a well defined pattern (without longitudinally interweaving strips with previously deposited strips). Before completing a layer assembly, with the exception of the last layer assembly, by depositing its last group of parallel strips, the first group of parallel strips of the following layer assembly is already deposited. A composite material manufactured with such a method is presented too.

  • Patent number: 8515677
    Abstract: Methods and apparatus are described to use real-time measurement systems to detect the onset of compression induced microfracturing of fiber-reinforced composite materials. Measurements are described to detect the onset of compression induced microfracturing of fiber-reinforced composite materials to prevent catastrophic failures of aircraft components containing such materials. Methods and apparatus are described to prevent fluids and gases from invading any compression induced microfractures by coating surfaces of fiber-reinforced materials to reduce the probability of failure of such fiber-reinforced materials.

  • Publication number: 20130183466
    Abstract: A compressible printing sleeve carrier for use in offset lithography which is formed from a composite fiber-reinforced compressible polymer is provided. The printing sleeve carrier is formed by coating reinforcing filaments with a compressible polymer and winding the filaments around a mandrel to form a hollow cylindrical base, where the first portion of the base adjacent the inner surface contains the wound reinforcing filaments coated with the compressible polymer and the second portion of the base adjacent the outer surface contains the compressible polymer.

    Abstract: Disclosed are methods and devices for the formation of fabric preforms that may be subsequently impregnated with a resin to form a composite component. One end of the fabric is received on the form such that the axial tows of the fabric extend in a direction generally perpendicular to a central axis of the form. At least some of the plurality of axial tows are separately tensioned on an end of the fabric not attached to the form and the fabric is wrapped around the form by rotating the fabric and form relative to one another about the central axis.

  • Patent number: 8455080
    Abstract: A protective sleeve for covering a wire harness. The protective sleeve includes an outer layer of a woven fabric extending a first length and a first width and having inwardly-facing surface and outwardly-facing surface. The protective sleeve also includes an adhesive layer applied over the inner-facing surface of the outer layer. The protective sleeve also includes an inner layer of non-woven fabric extending a second length and a second width less than the first width. The inner layer has an outwardly-facing surface adhered to the adhesive layer. The inner layer is centered on the outer layer such that two portions of the adhesive layer extend exposed along the first length on opposite sides of the second width.

  • Publication number: 20130075539
    Abstract: A composite structure for aerospace applications includes a structural member having multiple composite layers providing a longitudinally extending cavity. A conveyance element is arranged between and integral with the layers. In one example, the structural member provides a gas turbine engine duct or an airframe component. A composite structural assembly is manufactured by providing a first composite layer on a form that corresponds to a cavity. A second form, which may be a conveyance element in one example, is positioned along the first layer. A second composite layer is laid onto the second form and the first composite layer to provide a composite structural member with an integrated conveyance element.
