Abstract
A composite structural material and a method of making it, which material is thermoformable and capable of being rigidified by application of a resin, and which is useful in certain electronics applications because of a metallic layer incorporated within the structure. A layer of a selected metal is needle punched onto a fibrous batt of selected synthetic thermoplastic fibers, which is then thermoformed to a desired shape and rigidified by contacting with, and being embedded in, a suitable resin. Specific applications of the use of this composite include a parabolic dish-shaped antenna, an electromagnetic interference shield for electronic equipment, and a radioactive emission shield.
