摘要： A method and apparatus for forming an improved pultruded and clinched Z-axis fiber reinforced composite laminate structure. The upper and lower skins and the core are pulled automatically through tooling where the skin material is wetted-out with resin and the entire composite laminate is preformed in nearly its final thickness. The preformed composite laminate continues to be pulled into an automatic 3-dimensional Z-axis fiber deposition machine that deposits “groupings of fiber filaments” at multiple locations normal to the plane of the composite laminate structure and cuts each individual grouping such that an extension of each “grouping of fiber filaments” remains above the upper skin and below the lower skin. The preformed composite laminate then continues to be pulled into a secondary wet-out station. Next the preformed composite laminate travels into a pultrusion die where the extended “groupings of fiber filaments” are all bent over above the top skin and below the bottom skin producing a superior clinched Z-axis fiber reinforcement as the composite laminate continues to be pulled, catalyzed, and cured at the back section of the pultrusion die. The composite laminate continues to be pulled by grippers that then feed it into a gantry CNC machine that is synchronous with the pull speed of the grippers and where computerized machining, drilling, and cutting operations take place. This entire method is accomplished automatically without the need for human operators.

摘要： 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.

摘要： 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.

摘要： To produce a pultrusion which can be machined without undue strength loss bidirectional woven fiber fabric is modified to be pultrudable into a high shear strength composite member. In a preferred form of the invention the fabric is pleated in the pultrusion process to create an endless wall of stacked switchback pleated layers which defines a box beam wall in one example, and the shaft of a bolt in another. Products produced by this process have improved isotonic strength qualities over currently produced pultrusions, which are limited to unidirectional fibers, continuous fiber mats, or alternating layers of non-woven 0.degree. and 90.degree. cloth and do not have the shear strength inherent in the pleated configuration.
