Abstract
This invention relates to an electrically conductive shaped article made from thermoplastic materials which are reinforced with glass and steel fibers wherein said fibers are incorporated into the thermoplastic material by pultrusion. The amount of glass fibers incorporated into the thermoplastic material is such that the specific conductivity is at least 10% greater than in a shaped article in which the glass fibers are replaced by thermoplastic material. The shaped article can be used for shielding an article from electromagnetic radiation.
