【摘要】 采用镀金属炭毡与环氧树脂、聚丙烯（ＰＰ）、ＡＢＳ、聚苯乙烯（ＰＳ）、聚乙烯（ＰＥ）复合制备电磁屏蔽（ＥＭＳ）复合材料。镀金属炭毡复合材料在１～１０００ＭＨＺ范围内的屏蔽效率可达４０ｄＢ以上，不同的树脂体系对复合材料的屏蔽效率无显著影响，在炭毡纤维表面镀不同的金属对复合材料的屏蔽效率有较大的影响。更多还原

【Abstract】 EMS (Electromagnetic shielding) composites were manufactured by respectively laminating metal-coated carbon fiber felt with epoxy, PP, ABS, PS, and PE. The shielding effectiveness of the composites was higher than 40dB over a substantial frequency band from 1MHz to 1000MHz. The variety of resin was no significant effect on shielding effectiveness of composites. The properties of metal deposited on the surface of carbon fiber affected the shielding effectiveness of composites strongly.更多还原
