Research Progress in Interfacial Sizing Agent of Inorganic Fiber Reinforced Resins
In fiber reinforced plastic composites(FRPC),the interface between the fiber and the resin matrix determines whether the components can play a synergistic role,which has an important impact on the mechanical properties of FRPC,which is the key to FRPC design.Among the various strategies to improve interfacial properties,coating interfacial sizing agent on the fiber surface can effectively improve the interfacial compatibility and adhesive strength of fiber-resin and improve the overall performance of composite materials,so it has attracted much attention.In this paper,the sizing agent commonly used in basalt fiber(BF)and glass fiber(GF)is reviewed,the basic composition and function of sizing agent,the types of commonly used sizing agent,and the different components of sizing agent currently used for BF and GF and their corresponding modification mechanisms are analyzed,and the existing problems and future development of sizing agent are prospected.
