The present invention relates to composites useful for shielding electromagnetic radiation and their manufacture. In general, the composites of the present invention comprise conductive fibers which are highly dispersed in a polymer matrix. The invention also relates to pellets and their manufacture. Such pellets are useful in the manufacture of composites comprising highly dispersed conductive fibers in a polymer matrix.

Abstract:
The present invention relates to electrically conductive impregnated fibers and their method of manufacture. More particularly, the invention relates to a method for forming electrically conductive fibers by impregnating conductive fibers with an organic wetting agent to form an impregnated fiber tow and subsequently sheathed. Such sheathed impregnated tows can be formed into a wide variety of products such as radio-frequency and electromagnetic shielded plastic articles.
