Electromagnetic Shielding Effectiveness

The carbon fiber (CF) reinforced butadiene rubber (BR) electromagnetic shielding composite has been prepared by mechanical agitation and roll mixing methods. The composites have been characterized and tested. As shown in the experimental results, the mechanical properties was increased with the increase of CF, and the electromagnetic shielding effectiveness (SE) of BR based composite with 15 wt% CF content has been tested, the maximum SE was about 60 dB.

Electromagnetic Shielding Effectiveness

According to the results, when low melting polyester fiber increased to be 20%, the electromagnetic shielding/ far infrared ray nonwoven obtained the optimum burst strength, maximum breaking force and maximum tear strength, and they were as follows: burst strength was 4.2 kgf/cm2; maximum breaking force was 153.59 N in the cross machine direction and 70.80 N in the machine direction; maximum tear strength was 215.77 N in cross machine direction and 117.07 N in machine direction; and optimum electromagnetic shielding effectiveness (EMSE) was 45 dB.
