由于石墨纤维表面能较低,因此石墨纤维/树脂复合材料的界面粘合情况极为重要,为了阐明界面的粘合机理,需要对石墨纤维的表面特性如表面活化能、浸润性、表面积、表面化学基团等方面进行研究,为了提高复合材料的层间剪切强度,常常用各种方法对石墨纤维的表面进行处理,以期改变纤维表面的物理和化学结构来增加纤维和环氧树脂 Due to the low surface energy of graphite fiber, the interface bonding of graphite fiber / resin composite material is very important. To clarify the bonding mechanism of graphite fiber, the surface properties of graphite fiber such as surface activation energy, wettability, surface area, surface chemistry Groups and other aspects of research, in order to improve the interlaminar shear strength of composite materials, graphite fibers are often used in various ways to deal with the surface in order to change the physical and chemical structure of the fiber surface to increase fiber and epoxy resin
