One aspect of the present disclosure provides a composite body including: a nitride sintered body having a porous structure; and a semi-cured product of a thermosetting composition impregnated into the above-described nitride sintered body, in which dielectric breakdown voltage is 4.5 kV or higher.

Various systems are provided herein for sealing and dispensing the contents of containers. The systems can include openings that may be movable relative to one another between sealed positions and dispensing positions.

A composite cover includes a generally rectangular main portion having four main portion edges about a perimeter of the main portion and having opposing top and bottom surfaces defining respective upward and downward directions, and four generally rectangular side portions each contiguous with and extending downward from a respective one of the main portion edges. The main portion and the four side portions generally enclose an interior space and are made of a sandwich structure comprising an interior layer of continuous fiber reinforcements and resin and an exterior layer of metallic foil bonded to the interior layer. A method of manufacturing the cover, having a desired shape generally of a five-walled open box, includes attaching a formed sheet made of metallic foil and having the desired shape onto a shaped composite preform disposed in the desired shape, wherein the shaped composite preform is made of continuous fiber reinforcements and resin.

A multilayer protective covering can protect a surface from lightning strikes. The covering includes a bottom conductive layer affixed to the surface and having a first opening that is aligned with a grounding connection so that the grounding connection is exposed through first opening and not in contact with the bottom conductive layer. The covering also includes a dielectric layer affixed to the bottom conductive layer and having second opening aligned with the grounding connection so that the grounding connection is exposed through second opening and not in contact with the dielectric layer. The covering additionally includes a top conductive layer affixed to the dielectric layer and covering the grounding connection. The top conductive layer directs electrical current from a lightning strike on the surface to the grounding connection.
