Abstract：The interface engineering of composites has always been a hot research topic of carbon fiber reinforced polymer composites. The interphase acted as a “bridge” for transferring load between carbon fiber and resin matrix, and affected the implement efficiency of stiffness and strength of composites. Therefore, the design and adjustment of interphase played an important role in enhancing the interfacial properties and improving macro-mechanical properties of carbon fiber composites. In view of the influence factors such as surface physical and chemical characteristics of highstrength/high-modulus carbon fiber, the performance matching between carbon fiber and resin matrix and the different surface graphite-like structures, the correlation mechanisms of interface enhancement with the surface structure of carbon fiber and modulus of resin matrix were briefly outlined, and the research progress and interface enhancement effect of constructing new interphase of high temperature resistance and molecular assembly were reviewed. Finally, the development strategy of interphase with balance of rigidity and flexibility of carbon fiber composites was proposed.
