本文研究了液相氧化、电化学氧化和电化学聚合等表面处理对碳纤维的束丝强度和碳-酚醛复合材料的层间剪切强度的影响,并利用纤维的表面能和试件断口的扫描电镜形貌分析讨论了碳-酚醛复合材料中纤维与树脂界面的粘接机理。
In this paper, the effects of surface treatment such as liquid-phase oxidation, electrochemical oxidation and electrochemical polymerization on the strand strength of carbon fiber and the interlaminar shear strength of carbon-phenolic composites were investigated. The surface energy of fiber and the fracture of specimen were scanned Electron microscopic morphology analysis discussed the bonding mechanism between the fiber and the resin in the carbon-phenolic composite.
