  • Patent number: 9981421
    Abstract: Systems and processes that integrate thermoplastic and shape memory alloy materials to form an adaptive composite structure capable of changing its shape. For example, the adaptive composite structure may be designed to serve as a multifunctional adaptive wing flight control surface. Other applications for such adaptive composite structures include in variable area fan nozzles, winglets, fairings, elevators, rudders, or other aircraft components having an aerodynamic surface whose shape is preferably controllable. The material systems can be integrated by means of overbraiding (interwoven) with tows of both thermoplastic and shape memory alloy materials or separate layers of each material can be consolidated (e.g., using induction heating) to make a flight control surface that does not require separate actuation.

    Abstract: A method of forming an ordered nanorods array in a confined space is used to form a high surface area device where an ensemble of parallel trenches has micrometer dimensions for the width and depth of the trenches, which are decorated with crystalline nanowires radiating from the sidewalls and bases of the trenches. The high surface area device is formed by depositing a conformal crystalline seed coating in the trenches, forming microchannels from these trenches by placing a barrier layer on the open surface of the trenches, contacting the conformal coating with a crystal precursor solution that is caused to flow through the microchannels. In an embodiment, a very high surface area electrode is constructed with ZnO nanowires radiating from the sidewalls and base of trenches formed on a silicon substrate. The device can be a dye-sensitized solar cell.

  • Patent number: 7371699
    Abstract: A net-reinforced film structure includes a film layer and a netting attached to the film layer having a pattern of netting strands. The netting strands are sealed to an opposing film structure, which may be either a similar net-reinforced film or a standard sheet of film, along a linear seal area. The netting strands in the non-sealed areas of the net-reinforced film structure are free from attachment to the opposing film structure. The netting strands along the linear seal area have a wider cross-section than the netting strands at the non-sealed areas, and this wider cross-section facilitates the sealing process.

  • Patent number: 7041357
    Abstract: Apparatus and methods are presented for reinforcing and stiffening a printed circuit board (PCB) in selected locations by utilizing preferentially oriented fibers. Selected fibers within the polymeric material matrix of the PCB fiber-matrix layer are removed and replaced with a similar quantity of fibers in a preferential orientation. Various combinations of layering of modified fiber-matrix layer material with conventional fiber-matrix layer material are presented to achieve the desired PCB stiffening. Printed circuit boards, under the weight of heavy attached electronic components, may deflect or flex along an axis, defined as the characteristic fold. This flexing is exasperated with manufacturing and handling loading, particularly when mounted in a chassis. Preferentially orientated fibers laid transverse to the characteristic fold reinforces the area to resist flexure within the area surrounding the characteristic fold.
