Abstract: A method for protecting a substrate from lightning strikes is provided including providing a lightning strike protectant composition to the substrate. The lightning strike protectant composition comprises a reactive organic compound and a conductive filler that, during the cure of the organic compound, is capable of self-assembling into a heterogeneous structure comprised of a continuous, three-dimensional network of metal situated among (continuous or semi-continuous) polymer rich domains. The resulting composition has exceptionally high thermal and electrical conductivity.

Abstract: A protective system is provided including a material comprising a first and second surface opposite one another and a thickness, and where the first surface has a low-electrical resistance and the second surface has a high-electrical resistance that is higher than the electrical resistance of the low-electrical resistance surface, and the material conducts charge from the first surface to the second surface through the thickness. This can be provided in a bilayer structure where a first protective layer having a low-resistivity is disposed upon a second protective layer having a high-resistivity. This protective system is particularly useful for dissipating electrical charge, for example as a lightning strike protection system for composite aircraft.

Abstract: The present invention relates to processes for fabricating polymeric hollow fibers. Specifically, a removable solid core fiber is provided for coating one or more layers of a polymeric membrane-forming material thereon. After treating the polymeric membrane-forming material layer to form a solidified polymeric membrane having a permanent tubular shape, the solid core fiber is selectively removed, leaving an elongated lumen inside the solidified polymeric membrane, which forms a high quality polymeric hollow fiber that is substantially free of deformation defects. The solid core fiber can be made of a removable substrate material, such as water-soluble polymers polyvinyl pyrrolidone (PVP), polyvinyl alcohol (PVA), or polyethylene glycol (PEG), which are subsequently and selectively removable by water. Alternatively, the solid core fiber can be coated with a removable substrate material, which imparts removability to such solid core fiber.
