  • Patent number: 11834959
    Abstract: A morphing airfoil includes a dynamic flexible skin system that is capable of carrying high level aerodynamic (or fluid) pressure loads over a structural surface. The structural surface can morph and bend in response to control inputs to change a lift force without separate movable control surfaces. A plurality of standoff mounts is attached to an inner surface of anisotropic skin. The standoff mounts include through apertures for receiving a flexible stringer. The anisotropic skin is attached to underlying structure through the flexible stringers. The flexible stringers interface with actuated position control ribs and passive compliant support ribs. A control system causes the underlying support structure to move to a desired location which in turn causes the skin to bend and/or flex without exceeding a stress threshold and thus vary the lift and drag distributions along a span of the airfoil without separate control surfaces.

The adhesive can be selectively applied to or infiltrated within portions of the nanofibers comprising the nanofiber fabric. The adhesive enables connection of the nanofiber fabric to an underlying substrate, even in cases in which the underlying substrate has a three-dimensional topography, while the selective location of the adhesive on the fabric limits the contact area between the adhesive and the nanofibers of the nanofiber fabric. This limited contact area can help preserve the beneficial properties of the nanofibers (e.g., thermal conductivity, electrical conductivity, infra-red (IR) radiation transparency) that otherwise might be degraded by the presence of adhesive.

  • Patent number: 11092722
    Abstract: An optical absorber and method of manufacture is disclosed. A non-woven sheet of randomly-organized horizontally-oriented carbon nanotubes (CNTs) is subjected to a laser rasterizing treatment at ambient temperature and pressure. The upper surface of the sheet is functionalized by oxygen and hydrogen atoms resulting in improved absorbance properties as compared to untreated CNT sheets as well as to commercial state-of-art black paints. Laser treatment conditions may also be altered or modulated to provide surface texturing in addition to functionalization to enhance light trapping and optical absorbance properties.

  • Patent number: 11020914
    Abstract: A triaxial laid scrim includes a first, second and third set of continuous fibers. The fibers of each set are regularly spaced apart and are parallel to each other. The fibers of the first set are parallel to the warp direction or to the weft direction of the scrim. The fibers of the second set and the third set are oriented symmetrically to each other, respectively at an angle of 30°-80° with respect to the fibers of the first set. Distances between the fibers of the second set and the fibers of the third set are identical. The fibers of the second set cross the fibers of the third set at the intersection thereof with the fibers of the first set, thereby defining regular openings having an isosceles triangle shape. The fibers are coated and attached to each other by a coating that does not fill-up the triangle-shaped openings.

  • Patent number: 11008677
    Abstract: A woven sailcloth has groups of load-bearing yarns which extend in straight lines through tunnels without being woven. The tunnels are bordered front and back by woven layers and at the sides by crossing-over yarns. Because the load-bearing yarns extend along the tunnels there is no crimp in their longitudinal direction. The load-bearing yarns may include components for resistance to displacement along the tunnels, such as resin adhesives or wrapped-around filament.
