In this study, conductive polymer composites and conductive functional fabrics are combined to serve aselectromagnetic shielding planks. Polypropylene (PP), carbon black (CB), and short carbon fibers (SCF) are blended atdifferent ratios to form conductive polymer composites (i.e. PCS series). The mechanical property, electrical property,morphology, and electromagnetic interference shielding effectiveness (EMI SE) of the PCS series are evaluated. The testresults show that with 20 wt% of conductive fillers (i.e. CB and SCF), PCS20 exhibits the optimal tensile strength, flexuralstrength, and electrical property that is 7 order of magnitude higher than that of pure PP plates. Moreover, the EMI SE of thisgroup also reaches -30 dB, which meets level one of civil EMI SE standard. Therefore, PCS20 is used to combine with fourconductive sandwiches. The resulting multilayered functional PCS-sandwich planks are tested in terms of mechanicalproperty, morphology, and EMI SE. The test results show that the planks composed of a pure conductive woven sandwichhave the maximum tensile property and significantly improved impact resistance. All of the multilayered functional plankshave EMI SE that is higher than -50 dB and are qualified for the protection level of standard EMI SE electronic devices.
