  • Patent number: 10472473
    Abstract: Carbon fiber reinforced plastic (“CFRP”) composite layups and processes for manufacturing CFRP composite layups that integrate z-conductivity features directly into CFRP composite layups during the manufacturing processes for lightning protection, more particularly, inherent edge glow protection from lightning direct effects, and electrical current flow path control. CFRP composite layups are configured during the manufacturing processes to provide inter-ply electrical connections between composite plies of the CFRP composite layups, therefore avoiding the need for add-on protection features that result in significant cost and weight penalties.

  • Patent number: 10323415
    Abstract: A pregrouted PC steel material (10) includes a 19-wire-twisted PC strand (1), a pregrouted layer (2) disposed on an outer periphery of the PC strand (1), and a sheath (3) configured to cover an outer periphery of the pregrouted layer (2). A filling resin (4) is filled between steel wires (side wires) (1b, 1c, 1d). Since the filling resin (4) does not exude to the pregrouted layer (2) before tensioning of the PC strand (10), an operation of tensioning the PC strand (1) is not hindered by curing of the pregrouted layer (2). In contrast, since the gap between the steel wires is reduced when the PC strand (1) is tensioned, the filling resin (4) flows out (exudes) from between the steel wires to the pregrouted layer (2) to cure the pregrouted layer (2) only after the reduction.

  • Patent number: 10224068
    Abstract: A magnetic storage medium is formed of magnetic nanoparticles that are encapsulated within nanotubes, which are arranged in a substrate to facilitate the reading and writing of information by a read/write head. The substrate may be flexible or rigid. Information is stored on the magnetic nanoparticles via the read/write head of a storage device. These magnetic nanoparticles are arranged into data tracks to store information through encapsulation within the carbon nanotubes. As carbon nanotubes are bendable, the carbon nanotubes may be arranged on flexible or rigid substrates, such as a polymer tape or disk for flexible media, or a glass substrate for rigid disk. A polymer may assist holding the nanoparticle-filled carbon tubes to the substrate.
