Fiber-matrix interface is one of the most critical parameters controlling the performance of fiber-reinforced polymer composites (FRPs). During manufacturing of carbon/graphite fibers, sizing agent is applied on the fibers with a view to enhance the fiber-matrix bonding. However, it is customized for particular polymers, generally epoxies and hence not compatible for other polymers, especially thermoplastics. Hence, It is necessary to get rid of it first and then to apply appropriate one or to use a mechanism which will enhance the adhesion of de-sized fibers with the selected matrix. This work reports on the novel approach of Calcium hypochlorite treatment to the de-sized fibers, which led to the roughening of fibers as supported by FESEM (Field Emission Scanning Electron Microscopy) and AFM (Atomic force microscopy) analysis. Various methods such as matrix pick-up test, contact angle measurement, FTIR (Fourier-transform infrared spectroscopy) and XPS (x-ray photoelectron spect...

探索一种新的处理石墨纤维的方法，以增强纤维相对于基体的表面形貌

纤维-基质界面是控制纤维增强聚合物复合材料（FRP）性能的最关键参数之一。在制造碳/石墨纤维的过程中，为了增强纤维与基质的结合力，在纤维上施涂上浆剂。但是，它是针对特定的聚合物（通常是环氧树脂）定制的，因此不适用于其他聚合物，尤其是热塑性塑料。因此，有必要先消除它，然后再应用适当的一种或使用一种机制，该机制将增强退浆纤维与所选基质的粘合性。这项工作报告了对脱胶纤维进行次氯酸钙处理的新方法，这种方法在FESEM（场发射扫描电子显微镜）和AFM（原子力显微镜）分析的支持下使纤维变粗糙。
