Abstract

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.
