摘要
研究了镀镍碳纤维(NCF)增强工程塑料(PC/ABS)的制备和影响其屏蔽效能的因素。结果表明:镀镍碳纤维(NCF)增强工程塑料的力学性能和屏蔽性能与选择的加工设备、成型方法及纤维含量密切相关。当镀镍碳纤维(NCF)含量分别为10v%、25v%时,屏蔽效能值分别为30～40 dB、60～70 dB。
Conductive engineering plastics are important defensive and functional polymer composite materials for resisting electromagnetic interference（EMI）. In this paper, the preparation method and shielding effectiveness（SE） of PC/ABS composite engineering plastics with nickel-coated carbon fiber（NCF） are researched. The SE of the plastics could reach 30-40 dB and 60-70 dB by adding NCF 10v% and 25v% separately.
