ABSTRACT:
An article, such as a microwave waveguide filter, composed of a body of graphite fibre epoxy composite having thereon an electrically conductive layer comprising a thin flash of nickel on the body and a thicker layer of copper on the nickel. The invention also includes a process in which the body is provided with a smooth surface, this smooth surface is then deglazed, or given a slight roughness, a thin flash of nickel is deposited electrolessly on the roughened surface and a heavier coating of copper is electrolessly or electrolytically deposited on the nickel.
