碳纤维增强树脂基复合材料因性能优异而得到广泛应用。但由于碳纤维表面存在化学惰性,导致碳纤维与树脂基体间的界面结合性能一直是所制备的复合材料性能的短板,因此对碳纤维进行表面改性至关重要。等离子体处理可以极大地扩展纤维表面活性点并提高物理刻蚀程度,在此基础上的等离子体接枝技术能进一步增强纤维与树脂间的界面粘附力且工艺环保。对近年来国内外碳纤维表面等离子体改性方法进行了综述,以期为制备高性能碳纤维增强复合材料提供参考。
Carbon fibe r(CF) reinforced resin matrix composites are widely used because of their excellent properties.However,due to the chemical inertia on the CF surface,the interfacial adhesion between CF and resin matrix has always been the short board of the properties of the prepared composites.Therefore,the surface modification of CF is very important.Plasma treatment can greatly expand the fiber surface active points and improve the degree of physical etching.On this basis,the plasma grafting technology can further enhance the interfacial adhesion between fiber and resin,and the process is environmentally friendly.The plasma modification methods of CF surface at home and abroad in recent years were reviewed in order to provide reference for the preparation of high-performance CF reinforced composites.
