NRL

This invention pertains to a product and a method for preparing same. The product is an electrically conducting metallized fibers and a non-conducting composite containing the metallized fibers. In a preferred embodiment, the product is a composite of metallized cellulose fibers disposed in an electrically non-conducting matrix. The method includes the steps of hydrating cellulose fibers to prevent absorption of chemical reagents; activating the cellulose surface of the fibers for metal deposition; removing from the fibers excess activator and reagents used in the activation; drying the fibers to a free-flowing condition whereby the fibers acquire the color of the activator by virtue of its deposition on the fibers; metallizing the fibers to deposit thereon a metal capable of absorbing electromagnetic radiation; drying the metallized fibers whereby they are free-flowing; and forming a composite composed of an electrically non-conductive matrix having dispersed therein the matallized fibers.
