Abstract

In earlier machines, the exterior covers have been of formed metal or of plastic parts. Metallic parts are satisfactory for shielding to prevent electromagnetic radiation or outside interference but plastic parts have required a metal plating and elaborate connecting provisions to ensure complete grounding.

Electroconductive Polymers for Electromagnetic Compatibility

In earlier machines, the exterior covers have been of formed metal or of plastic parts. Metallic parts are satisfactory for shielding to prevent electromagnetic radiation or outside interference but plastic parts have required a metal plating and elaborate connecting provisions to ensure complete grounding.

By making the covers of the plastic body of a plastic which is reinforced with either carbon fibers or metal-coated glass fibers, the covers can be sufficiently conductive to provide the necessary shielding. This will provide inexpensive covers, since there will be no need for the special operations needed to provide the shielding properties.
