摘要
本文用X射线光电子能谱分析了不同电解质电化学氧化后碳纤维的表面基因,探讨了碳纤维表面结构对碳纤维复合材料的层间剪切强度的影响规律.结果表明,层间剪切强度与碳纤维表面C=O的数量间呈非线性相关关系,与C=O类呈不显著的线性相关关系,与COOH类和纤维表面含氧官能团的总数之间分别呈显著的线性相关关系.
The surface group of carbon fibres was investigated by X -ray photoelectron spectroscopy(XPS) in this paper. On the basis of the XPS analysis, the relationship between the ILSS of CFRP and surface structure of carbon fibres was studied. It is indicated that there exist a non-linear correlation between the amount of carboxyl on carbon fibre surface and the ILSS, a weak correlation between C = 0 group and the ILSS, and a notable significant correlation between the total, amount of surface oxygen containing groups and the ILSS.
