本文主要研究了不同碳纤维(CFs)与环氧树脂之间的润湿行为随温度、固化剂加入量和树脂逐步固化的变化规律。结果表明，表面施胶对碳纤维与环氧树脂的润湿性起着关键作用。DGEBA-DDS混合物/CF有一个润湿良好的临界温度。树脂/碳纤维复合材料固化一段时间后即可达到完全润湿。此外，化学反应不仅可以改善树脂的润湿性，而且可以加强固化树脂与碳纤维之间的相互作用。这些结果对理解碳纤维/环氧复合材料相界面区的形成过程具有重要意义。2012年威利期刊公司J.应用。波兰姆。SCI。2000：000-000,2012年
This article focuses on experimental studies on the wetting behavior between different carbon fibers (CFs) and epoxy as function of temperature, hardener addition, and progressive curing of the resin. The results indicate that surface sizing plays a key role in wettability of the CF with epoxy. There is a critical temperature for good-wetting of DGEBA-DDS mixture/CF. Complete wet- ting can be obtained for resin/CF after a period of curing time. Moreover, chemical reactions can not only improve the wettability but also strengthen interactions between the curing resin and CF. These results could provide an essential implication for understand- ing the formation process of interphase region of CF/epoxy composites. V C 2012 Wiley Periodicals, Inc. J. Appl. Polym.
