Description 616-622
The surface of the carbon fiber (CF) has been pretreated by liquid phase deposition of microcrystalline cellulose (MCC). X-ray photoelectron spectroscopy, atomic force microscopy (AFM) and scanning electron microscopy (SEM) have been used to analyze and characterize the surface morphology and structure of carbon fiber, and the shear strength test and SEM observation of single fiber interface have been performed. The interfacial adhesion properties of carbon fiber composites have been investigated. The results have shown that the pretreated carbon fiber deposition increases the shear strength of the single fiber interface by 259.3%. The analysis results have shown that the improvement of interfacial shear strength has been related to the mechanical riveting between the fibers/resin and the force of the interface. Pretreatment has increased the carboxyl groups on the surface of carbon fibers and forms hydrogen bonds between carboxyl groups, thereby improving the interfacial properties of carbon fiber composites.
