Study on the Process and Properties of Nickel Coated Carbon Fiber Functional Integrated Composites Subtitle as Needed

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,利用热压罐制备了镀镍碳纤维一体化复合材料。 研究了复合材料热压罐成型过程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:经过铺层设计后热压成型复合材料的拉伸强度为898 GPa,电流密度A = 5 A/dm2、电镀时间为6 min,此时镍镀层与碳纤维结合强度较好,铺层角度为0?/90?/0?,铺层厚度为3 mm时,复合材料的屏蔽效能75~112 dB (100 kHz^18 GHz)。

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 prop-erties 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 898 GPa, A = 5 A/dm2, current density and plating time is 6 min, the nickel coating and carbon fiber with good strength, ply angle of 0?/90?/0?, the layer thickness is 3 mm, the shielding effectiveness of composites 75 - 112 dB (100 kHz - 18 GHz).
