在这项工作中，提出了一种基于碳纤维表面纳米级Ni-P合金涂层的新方法，用于改善复合材料系统中纤维与环氧树脂基体之间的界面性能。通过原子吸收分光光度计（AAS）、扫描电子显微镜（SEM）、X射线光电子能谱（XPS）、层间剪切强度（ILSS）和冲击强度表征复合材料的纤维表面和机械界面性能。实验结果表明，随着化学镀镍的进行，O(1s)/C(1s)比值或Ni、P含量增加； ILSS 也略有改善。碳纤维表面存在Ni-P合金时，冲击性能显着改善，增加了复合材料的延展性。这可能是由于取代的Ni-P合金的作用，导致环氧树脂体系的抗变形和裂纹萌生能力增加。
In this work, a new method based on nanoscaled Ni-P alloy coating on carbon fiber surfaces is proposed for the improvement of interfacial properties between fibers and epoxy matrix in a composite system. Fiber surfaces and the mechanical interfacial properties of composites were characterized by atomic absorption spectrophotometer (AAS), scanning electron microscopy (SEM), X-ray photoelectron spectrometry (XPS), interlaminar shear strength (ILSS), and impact strength. Experimental results showed that the O(1s)/C(1s) ratio or Ni and P amounts had been increased as the electroless nickel plating proceeded; the ILSS had also been slightly improved. The impact properties were significantly improved in the presence of Ni-P alloy on carbon fiber surfaces, increasing the ductility of the composites. This was probably due to the effect of substituted Ni-P alloy, leading to an increase of the resistance to the deformation and the crack initiation of the epoxy system.
