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.

A contoured composite comprising: a sheet of foil; a substrate, which substrate is nonwoven batt of fibers of at least one synthetic thermoplastic resin; the foil being tacked onto the substrate by a needle loom to form a composite; and the substrate fibers, having the property of softening when heated for a period of time to the temperature of their softening point and subsequently rehardening when cooled for a period of time, taking the shape of a predetermined contour against which the composite is set during at least part of the heating and cooling periods.
