通过真空镀膜技术制备了一种新型镀Ni碳纤维板复合材料,用扫描电镜(SEM)、X射线衍射(XRD)、红外成像仪对其进行表征分析和温度测试。结果表明:复合材料具有优良的涡流加热能力,样品表面沉积量和输入功率的变化能直接影响样品表面导电网络的构建和升温能力。随着沉积量的变化,在恒定输出功率123W情况下,Ni/CFB-100样品的最高温度可以达到123℃,而Ni/CFB-600样品的最终温度达到142.5℃。随输入功率的变化,Ni/CFB-600样品在输入功率44W下的升温幅度只有40.2℃,但在输入功率123W下的升温幅度达到了86.4℃。在恒定输入功率情况下,Ni/CFB-600样品的最大融冰速率达到了20.161×10-3g/s。实验表明在导电性能较差的碳纤维板表面通过真空镀膜技术镀镍可以实现涡流加热除冰的目的,具有潜在的应用价值。

A new type of Ni-coated carbon fiber board composite was prepared by vacuum coating technique.The composite was characterized by (SEM),X-ray diffraction (XRD),infrared imaging (FT-IR) and scanning electron microscope.The experiment shown that the composite had excellent eddy current heating ability.The change of deposition amount and input power can directly affect the construction and heating capacity of the sample surface conductive network.With the change of deposition amount,when the input power was 123W,the maximum temperature of Ni/CFB-100 sample can reach 123℃,and the final temperature of Ni/CFB-600 sample can reach nearly 142.5℃.With the change of the input power,the heating range of the Ni/CFB-600 sample was only 40.2℃ at the input power 44W,but it reached 86.4℃ at the input power 123W.Under the condition of constant input power,the maximum melting rate of Ni/CFB-600 samples was up to 20.161×10-3g/s.The experimental results shown that nickel plating on the surface of carbon fiber board with poor conductivity can achieve the purpose of eddy current heating and deicing,which had potential application value.
