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.

A cutting method for an elastic membrane material and an elastic filament manufactured with the cutting method. The cutting method includes: preparing an elastic membrane material with flexibility; temporarily bonding the elastic membrane material with a cushion layer to form a semi-finished membrane material and supporting the elastic membrane material by the cushion layer; pulling the semi-finished membrane material continuously, and cutting the elastic membrane material into a plurality of filaments with a cutting device during the pulling process; and separating the cut filaments from the cushion layer, the separated filament being the elastic filament, and the elastic filament can be made into an elastic filament with functionality and special appearance. A fabric woven with the elastic filament has the effects of softness, close-fitting, excellent tactile impression and flexible. A functional layer can be provided on a surface of the elastic filament to make the elastic filament to have luminescent, reflective or conductive function.

A method for producing a black plated resin part includes the steps of electroplating a resin substrate provided with an underlying plating layer in a trivalent chromium plating bath containing thiocyanic acid, to thereby form, on the underlying plating layer, a black chromium plating layer composed of trivalent chromium and having a thickness of 0.15 μm or more; and immersing the resin substrate provided with the black chromium plating layer in warm water at 30° C. or higher for a predetermined time. In the method, the amount of thiocyanic acid contained in the trivalent chromium plating bath, the temperature of the warm water, and the time of immersion of the resin substrate in the warm water are adjusted so that the black chromium plating layer exhibits a b* value of −1.7 or less based on the L*a*b* color system.

A sliding member includes a back-metal layer including an Fe alloy and a sliding layer including a copper alloy including 0.5 to 12 mass % of Sn and the balance of Cu and inevitable impurities.
