  • Patent number: 9919785
    Abstract: A stringer made of composite material for reinforcing aircraft skin panels. Plies are introduced at 90° in a segment close to the stringer run-out, and progressively reducing the number of plies at 0°, such that the majority of the number of plies is at 90° in an segment adjacent to the run-out, so the stiffness of the run-out is reduced, and the load it supports is also therefore reduced. This is an alternative solution to the solutions already existing for getting the stringer run-outs to support a smaller load, thereby reducing both the risk of the plies of the stringer peeling off and the risk of separation between stringer and skin panel. A method of manufacturing said stringer is also provided.

  • Patent number: 9777455
    Abstract: A water-permeable woven geotextile fabric for providing soil reinforcement and/or stabilization, for example as an underlayment in road construction, utilizes a series of round warp fibers, in combination with a series of flat warp fibers, across the width of the fabric to increase water flow while still providing desired filtration. In particular, the round warp fibers form angles that allow greater amounts of water to pass through the fabric. In addition, using both round and flat warp fibers results in increased roughness of the fabric surface, which makes the fabric more resistant to being pulled out of the soil when pulled on. Furthermore, one or more of the round and/or flat warp fibers can include a color selected for high visibility to the human eye in daylight conditions.

  • Patent number: 9469079
    Abstract: A cover member of an illuminating unit is formed of a film insert molded product, in which a film is disposed on a decorative face. The film is arranged so an end part of the film is positioned in front of an end part of the decorative face, whereby a film end protecting area formed of an exposed part of a molded resin layer is provided between the end part of the decorative face and the end part of the film, and a surface of the film end protecting area is made flush with the surface of the film. A corner between the end part of the decorative face and an end face of the molded resin layer is set to be an acute angle, and the end face of the molded resin layer functions as a contact face with respect to a ceiling trim.

  • Patent number: 9381702
    Abstract: Methods creating composite preforms with a three-dimensional weaving pattern include stacking material layers and then connecting them with interlayer reinforcements. First and second layers are aligned and separated by a first layer spacing. First interlayer reinforcements are then inserted through at least the first and the second layers. At least a third layer is aligned with at least the first and second layers. Second interlayer reinforcements are inserted through at least the second and third layers, using the first layer spacing between the first and second layers to manipulated the second interlayer reinforcements during insertion. Following the insertion of at least the second interlayer reinforcement, this layer spacing is closed to bring the first and second layers into contact. Further layers and interlayer reinforcements may be added, using additional layer spacings to manipulate additional interlayer reinforcements to form complex three-dimensionally woven composite preforms.

  • Patent number: 9354421
    Abstract: Provided is an advanced grid structure manufactured by a lamination step of laminating a first tape prepreg group, a second tape prepreg group, and a third tape prepreg group repeatedly in the stated order on a forming die, in which grooves (2, 3, 4) in a lattice shape are formed in three directions, so as to provide crossing regions (7, 8, 9) in which two tape prepreg groups overlap each other, and a heating forming step of forming a laminate by heating under pressure. In the lamination step, the first tape prepreg group, the second tape prepreg group, and the third tape prepreg group are respectively laminated as one layer in crossing regions (7, 8, 9) so that a tape width is maintained, and laminated in non-crossing regions (2a, 3a, 4a) in a state of being folded as two layers in a width direction thereof.

  • Patent number: 9333732
    Abstract: A product sheet of composite material can be made by disposing composite materials of composite material in adjacent (side-by-side) relation with each other. The composite materials comprise fibers in a thermoplastic matrix material. The adjacent composite materials are bonded together to provide a product sheet of composite material. Preferably, a cross ply of composite material is disposed on the composite materials. The cross ply may be a unidirectional sheet and the fibers in the cross ply may be disposed in transverse relation to the fibers in the composite materials.

    Abstract: In accordance with the present teachings, a method of producing composite having a 3A Q3D reinforcement phase is disclosed. The method of producing the composite provides producing a three-dimensionally woven configuration where a first fiber from a first sheet of reinforcement phase is interwoven or mechanically linked with at least one of an adjacent second layer and then back into the first sheet. The linking fibers are passed between layers at an acute angle generally less than about 10 degrees. The method includes impregnating the woven construction with a curable polymer such as epoxy.

  • Patent number: 9259896
    Abstract: Doctor blade material, which is composed of a number of layers that are connected to each other and include at least a frame layer. The frame layer, includes outer layers on both sides and is constructed of carbon fiber and/or mineral fiber, e.g. glass fiber, basalt fiber, et cetera. The outer layers include carbon fiber. The outer layer is a compact-multiaxial layer composed of a surface layer containing carbon fiber and of two or more support layers. The surface layer includes carbon fibers that are at a 90° angle with respect to the longitudinal direction of the doctor blade, wherein the fibers in the first support layer following the surface layer are at an angle between (?70°)-(?20°) or (+20°)-(+70°) with respect to the fibers of the surface layer. The fibers in the second support layer following this are at an angle between (+20°)-(+70°) or (?70°)-(?20°) with respect to the fibers of the surface layer.

  • Patent number: 9248624
    Abstract: The invention relates to reinforcing fiber scrims, comprising multi-layer, multiaxial scrims, which each comprise individual fibers arranged next to each other in a layer, wherein at least two layers are at an angle to one each other in the layer plane and are connected by a fixing means. To improve the processing of the multiaxial scrims and significantly reduce the processing time, at least two prefabricated MD scrims are arranged at an angle in a layer plane and connected to each other. Thus a reinforcing fiber scrim is provided, which has at least two individual fiber scrims and which, for a 0° position of the individual MD scrims, has six individual fiber scrims. The number of MD scrims arranged one over the other can be arbitrarily increased so that an increased layer structure is already present when the reinforcing fiber scrim is produced.
