| 20110104433 | Composite Laminate Structure - A composite laminate structure includes a first skin; a second skin; and a plurality of distinct groupings of Z-axis fibers that extend from the first skin to the second skin, wherein the Z-axis fibers include opposite ends respectively terminating at and integrated into the first skin and the second skin. | 05-05-2011 |
| 20090214849 | Composite Laminate Structure - A composite laminate structure includes a first skin; a second skin; a core between the first skin and the second skin, the core including adjacent core sections and a Z-Y partition separating the adjacent core sections; and a plurality of distinct groupings of Z-axis fibers that extend from the first skin to the second skin through the adjacent core sections and the Z-Y partition separating the adjacent core sections. | 08-27-2009 |
| 20090071594 | Method of Inserting Z-Axis Reinforcing Fibers into a Composite Laminate - A method of inserting z-axis reinforcing fibers into a multi-layer composite laminate. Layers of material made up of z-axis fiber and y-axis fibers are automatically transported into a z-fiber deposition machine having a housing with upper and lower surfaces. Z-axis apertures are formed in the respective upper and lower surfaces. An elongated solid rod having a tapered front tip is aligned in close proximity to the aperture in the bottom surface. The rod is first rotated by a motor and then actuated upwardly completely through the thickness of the layer of x-y material by an actuator. A first hollow tube having a z-axis is axially aligned with the aperture in the top surface and a fiber bundle is threaded downwardly through a first hollow tube to a position adjacent its bottom end. The z-fiber deposition machine has structure to feed a predetermined length of the fiber bundle downwardly through the first hollow tube so that it follows the pathway in the x-y material formed by the rod which is now withdrawn downwardly through the aperture in the bottom wall. The z-axis fiber is thus deposited into the x-y material. The top end of the z-axis fiber is then severed and the x-y material is then advanced a predetermined distance to complete the cycle and is, thus, set to be repeated. | 03-19-2009 |
| 20080314017 | System and Method for Maintaining the Location of a Fiber Doff Inner-Diameter-Tow at the Point of Payout Within a Constant Inertial Reference Frame - A method of maintaining the location of a fiber doff inner-diameter-tow at a point of payout within a constant inertial reference frame includes providing a flat fiber tow payout system with a center-pull doff of flat fiber tow that pays out at a point of payout along an inner diameter of the center-pull doff with rotation of the center-pull doff about a vertically oriented axis of rotation, the flat fiber tow payout system including a constant inertial reference frame for payout of the flat fiber tow along the inner diameter of the center-pull doff without twisting the flat fiber tow; and accelerating and stopping rotation of the center-pull doff with the flat fiber tow payout system so as to maintain payout of the flat fiber tow along the inner diameter of the center-pull doff in the constant inertial reference frame, preventing twisting of the flat fiber tow. | 12-25-2008 |
