What are the main factors that affect the strength of carbon fibers?
[Abstract]: the interface play on the properties of carbon fiber composite material plays a very important role, the composite load transfer through the interface, can make the carbon fiber and the matrix to form an effective performance of the whole. In the study of the interface, improving the bonding strength is the key to improve the mechanical properties of the carbon fiber composite. Therefore, it is very important to analyze the influence of various factors on the interfacial bonding strength of carbon fiber reinforced composites for improving the comprehensive properties of composites. In this paper, by using scanning electron microscopy (SEM), X ray photoelectron spectroscopy (XPS), laser Raman spectroscopy (LRS), X ray diffraction (XRD) and Fu Liye transform infrared spectroscopy (FTIR) and mechanical testing technology, investigated the effect of different preparation processes on the structure and properties of carbon fiber, discusses the evolution of the structure and properties of the carbon fiber surface process and electrochemical treatment in the process of electrochemical modification prepared by wet spinning PAN based carbon fiber, the carbon fiber surface except the rationality of glue craft, in-depth study of the carbon fiber electrochemical treatment, sizing agent and matrix modification effect on the bonding strength of carbon fiber composite the carbon fiber material, electrochemical modification mechanism and matrix modification mechanism.
