The performance of carbon fibre-reinforced composites is dependent to a great extent on the properties of fibre-matrix interface. In this research, based on the reviewed surface modification technique and inspired by the in situ growth of three-dimensional graphene coatings on nanomaterials, a new method of in situ growth of a graphene-related structure on the surface of carbon fibres is to be applied, for which it is intended to use a mixed solution of Ferrous Sulfate Heptahydrate (FeSO₄· 7H₂O) and D-Glucose monohydrate (C₆H₁₂O₆ · H₂O) to treat the carbon fibres under specific conditions to in-situ growth of a graphene-related coatings on the surface of carbon fibres. Firstly, the method was carried out by heating the mixed solution under specific temperature on the silicon wafer substrate and followed with characterisation experiments such as Raman and Scanning Electron Microscopy (SEM). Then, the mixed solution was applied on the carbon fibres and treated under the same condition. The characterisation results indicated successfully growth of the porous carbon coatings on the surface of the carbon fibres, which contained with graphene-related structures, while other characterization experiment like Transition Electron Microscopy (TEM) and X-ray Photoelectron Spectroscopy (XPS) will need to be used to further characterise the porous carbon structure. The interfacial shear strength between the fibre and the porous carbon coating also need to be characterised by using the micro-bond test.

碳纤维增强复合材料的性能在很大程度上取决于纤维-基质界面的性能。在这项研究中，基于回顾的表面改性技术，并受在纳米材料上原位生长三维石墨烯涂层的启发，将应用一种在碳纤维表面原位生长石墨烯相关结构的新方法，打算使用七水合硫酸亚铁（FeSO ₄ ·7H ₂ O）和一水合D-葡萄糖（C ₆ H ₁₂ O ₆ ·H ₂）的混合溶液O）在特定条件下处理碳纤维，以在碳纤维表面上原位生长石墨烯相关涂层。首先，通过在特定温度下在硅晶片基板上加热混合溶液并随后进行诸如拉曼和扫描电子显微镜（SEM）的表征实验来进行该方法。然后，将混合溶液施加到碳纤维上，并在相同条件下进行处理。表征结果表明，多孔碳涂层在碳纤维表面上成功生长，该涂层包含石墨烯相关的结构，而其他表征实验（例如过渡电子显微镜（TEM）和X射线光电子能谱（XPS））则需要用于进一步表征多孔碳结构。
