摘要

为了提高碳纤维/聚酰亚胺(CF/PI)复合材料的界面性能，采用电泳沉积的方法在碳纤维表面引入硅烷化反应碳纳米管(CNTs)制备CF/CNT/PI复合材料。研究了碳纤维表面处理对复合材料力学性能的影响。结果表明，复合材料的层间剪切强度和弯曲强度分别提高了11%和9%。采用扫描电镜和原子力显微镜(AFM)对复合材料界面相的精细结构进行分析。结果表明，CNTs的引入在纤维和基体之间形成了CNTs增强PI树脂的界面过渡层。

The effect of electrophoretic deposition of carbon nanotubes on carbon fiber on interfacial properties of the thermoplastic polyimide composite

In order to improve the interfacial properties of carbon fiber/polyimide (CF/PI) composite, silanization reaction carbon nanotubes (CNTs) were introduced to the surface of carbon fiber by electrophoretic deposition to prepare CF/CNT/PI composite. The effects of carbon fiber surface treatment on the mechanical properties of the composites were studied. The results showed that the interlaminar shear strength and bending strength of the composite materials were increased by 11% and 9%, respectively. The scanning electron microscope and Atomic Force Microscope (AFM) was used to analyze the fine structure of composite interface phase. The results show that the introduction of CNTs creates an interface transition layer of CNTs reinforced PI resin between the fiber and the matrix.

期刊介绍： Surface and Interface Analysis is devoted to the publication of papers dealing with the development and application of techniques for the characterization of surfaces, interfaces and thin films. Papers dealing with standardization and quantification are particularly welcome, and also those which deal with the application of these techniques to industrial problems. Papers dealing with the purely theoretical aspects of the technique will also be considered. Review articles will be published; prior consultation with one of the Editors is advised in these cases. Papers must clearly be of scientific value in the field and will be submitted to two independent referees. Contributions must be in English and must not have been published elsewhere, and authors must agree not to communicate the same material for publication to any other journal. Authors are invited to submit their papers for publication to John Watts (UK only), Jose Sanz (Rest of Europe), John T. Grant (all non-European countries, except Japan) or R. Shimizu (Japan only).
