Abstract:	Polycarbonate (PC) polymers mixed with conductive stainless steel fiber (SSF) is injection-molded under various injection process conditions. The composite formed is then tested for its capability to shield off electromagnetic field passing through. The effects of four major injection processing parameters including melt temperature, mold temperature, injection velocity and packing pressure on the electromagnetic interference (EMI) shielding effectiveness (SE) of PC filled with conductive SSF have been investigated. Taguchi method is adopted to obtain the optimum set of injection process parameters to acquire the maximum EMI shielding. It is observed that melt temperature and packing pressure significantly affect shielding effectiveness performance for injection-molded PC composites with SSF filter. (C) 2008 Elsevier Ltd.
