摘　　要：采用连续电镀法对碳纤维进行镀镍处理,经镀镍碳纤维编制成镀镍碳纤维布,以环氧为基体树脂,镀镍碳纤维为增强材料,制备了镀镍碳纤维一体化复合材料。研究了复合材料铺层设计对复合材料力学性能以及屏蔽性能的影响。通过扫描电子显微镜分析镀层的外观外貌。结果表明:通过测试复合材料的拉伸强度为898GPa;当电流密度A=5A/dm^2、电镀时间为6min时,此时镍镀层与碳纤维结合强度较好复合材料的屏蔽效能75-112dB( 100kHz-18GHz)。carbon fiber was plated with nickel by continuous electroplating method, and nickel carbon fiber cloth was prepared by nickel plated carbon fiber, and nickel carbon fiber composite material was prepared by hot pressing pot with epoxy resin as matrix resin and nickel plated carbon fiber as reinforcing material. The effect of layer design on the mechanical properties and shielding properties of composite hot pressing tank was studied. The appearance of the coating was analyzed by scanning electron microscope. The results showed that after the overlay design after hot pressing the tensile strength of the composite was 898GPa, A =5A/dm^2, current density and plating time is 6min, the nickel coating and carbon fiber with good strength, the layer thickness is 3mm, the shielding effectiveness of composites (75-112 dB 100kHz-18GHz).
