Abstract:
The present invention presents an SMC with which the electrically conductive layer does not break down or become non-uniform during molding and with which molded articles with excellent electromagnetic wave shielding capability and electric conductivity can be produced. This SMC is a thermosetting resin sheet molding compound having at least one continuous layer of electrically conductive fibers with a fiber length of 50 &mgr; to 5 mm, and it is further preferred that electrically conductive powder is uniformly dispersed throughout the entire molding compound. These SMCs can be produced by impregnating a reinforcing material with a thermosetting resin composition which is combined with the above-mentioned electrically conductive fibers, or the electrically conductive fibers and electrically conductive powder, and forming at least one continuous layer of these electrically conductive fibers adjacent to this reinforcement layer.
