In this study, the use of polyester fiber cloth for the fabric, activated carbon powder and iron powder according to the different weight percent concentration were mixed to the unsaturated polyester resin, respectively, on coating on the fabric and matching laminated. The
activated carbon and iron powder weight percent concentration of 5%, 10%, 15%, 20%, 25%,respective explore different matching methods, and with geometric patterns and for different spacing of 1 cm, 1.5 cm, 2 cm the change to explore the effect of the electromagnetic wave absorption values by adding the square pattern spacing of 1 cm, matching the toner weight of the top-level activity percentile concentration of 25%, the middle layer of iron 15% 25% activated carbon powder with a square pattern, the lowest level of iron powder 15% 25% activated carbon
powder with a square pattern, the electromagnetic wave absorption values of up to 36dB.
