    Abstract: Various automated fiber placement systems and methods are disclosed. The system can determine steerable paths for the application of a composite material over highly contoured surfaces. The system can determine when a course trajectory would violate a steering limitation (e.g., a maximum bendability of the composite material) and can adjust the trajectory to avoid such violations. The adjustment can create gaps between adjacent courses, which can have a generally flared peripheral shape. The system can fill such gaps with subsequent courses of the composite material. Thus, the system can automatically apply composite material to highly contoured surfaces while also avoiding violation of the steering limitations.

  • Patent number: 9221236
    Abstract: Methods of and systems for assembling stiffened composite structures are disclosed. Some methods include loading a stiffener onto an inner mold line layup mandrel and then loading a filler structure within the stiffener cavity of the stiffener. Some methods include loading, with a loading tool, a stiffener charge and a filler structure onto an inner mold line layup mandrel so the respective stiffener charge conforms to a stiffener form of the inner mold line layup mandrel to form a stiffener. Some methods include loading, with a loading tool, a stiffener and a filler structure onto an inner mold line layup mandrel.

  • Publication number: 20150133245
    Abstract: A cylindrical carbon fiber arrow shaft formed with an exterior surface having single or multiple outside diameters and formed with an axial bore having multiple interior diameters. In a preferred embodiment, the exterior surface of the arrow shaft has an increased external diameter at the nock end and tapers to a smaller external diameter at the tip end. The axial bore has an internal diameter at the nock end corresponding to standard arrows having external diameters of 0.295 inches and tapers to a smaller internal diameter at the tip end. Modifying the length, diameter, and wall thickness of the arrow shaft varies the stiffness of the arrow shaft along the length and shifts the center of gravity along the length of the arrow shaft and as well. Utilizing standard internal diameters, nock and tips may be attached without spacers or inserts, thereby decreasing weight of the arrow significantly.
