Demand for the natural and synthetic fibres are increasing day by day due to the development of high strength composites materials, especially in the production of polymer/ceramic matrix composites. Various types of fibres such as carbon fibres, SiC fibres, polymer fibres and metal fibres were used in the fabrication of composite materials. Despite the strength of the fibres, poor interfacial bonding between the matrix and fibre limits the mechanical strength of the composites. Hence, researches were focused on the application of various surface treatments and coatings on the surface of fibres to augment the interfacial bond/strength of the composites. Researchers improved the fibre properties like adhesion and conductivity through surface coating techniques. So, it is important to review the influence of various surface coatings (polymer, ceramic, metallic and carbon) and chemical treatments on the mechanical strength of the fibres, which could pave the way for the discovery of novel composite materials in the near future. The present article comprehensively reviews the various surface coatings and treatments on fibres and its impact on the wettability, phase composition, interfacial bonding, mechanical strength and thermal conductivity. Hence, this review article could be as a reference hub for the researchers working on the coating and treatments on the fibres to augment its surface characteristics further.

由于高强度复合材料的发展，特别是在聚合物/陶瓷基复合材料的生产中，对天然和合成纤维的需求日益增加。各种类型的纤维如碳纤维、碳化硅纤维、聚合物纤维和金属纤维被用于制造复合材料。尽管纤维具有强度，但基体和纤维之间较差的界面结合限制了复合材料的机械强度。因此，研究的重点是在纤维表面应用各种表面处理和涂层，以增加复合材料的界面结合/强度。研究人员通过表面涂层技术改善了纤维特性，如附着力和导电性。因此，回顾各种表面涂层（聚合物、陶瓷、金属和碳）以及对纤维机械强度的化学处理，这可能为在不久的将来发现新型复合材料铺平道路。本文全面回顾了纤维上的各种表面涂层和处理及其对润湿性、相组成、界面结合、机械强度和热导率的影响。因此，这篇评论文章可以作为研究人员在纤维上进行涂层和处理以进一步增强其表面特性的参考中心。本文全面回顾了纤维上的各种表面涂层和处理及其对润湿性、相组成、界面结合、机械强度和热导率的影响。因此，这篇评论文章可以作为研究人员在纤维上进行涂层和处理以进一步增强其表面特性的参考中心。本文全面回顾了纤维上的各种表面涂层和处理及其对润湿性、相组成、界面结合、机械强度和热导率的影响。因此，这篇评论文章可以作为研究人员在纤维上进行涂层和处理以进一步增强其表面特性的参考中心。
