表面粗糙度和含氧官能团对炭纤维/环氧树脂界面黏结的贡献
Contribution of surface roughness and oxygen-containing groups to the interfacial shear strength of carbon fiber/epoxy resin composites
摘要
Abstract
The interfacial shear strength(IFSS)between carbon fibers(CFs)and the matrix is crucial to the performance of CF-reinforced polymer composites.To evaluate the contribution of mechanical interlocking and chemical anchoring at the interfaces of a polyacrylonitrile-based CF(TORAYCA T800SC-12000-10E)-reinforced epoxy resin(EP:bisphenol A type epoxy resin and tet-rafunctional epoxy resin)composites,the surface roughness and content of oxygen-containing functional groups of the CFs were re-spectively altered by ammonia treatment and electrochemical oxidation.The results showed that ammonia treatment increased the surface roughness without much change to the surface elemental composition,while electrochemical oxidation increased the number of surface oxygen groups without changing the surface roughness.The IFSS of CF/EP composites was tested by the micro-droplet method.The relationships between IFSS,and surface roughness and oxygen content were obtained by linear fitting.The results showed that in the interfacial bonding of CF to epoxy resin,the contribution of chemical anchoring to the IFSS is larger than that of mechanical interlocking.关键词
