Carbon fiber reinforced resin matrix composites(CFRP)have emerged as materials of significant research interest,owing to their relevance in achieving national objectives related to carbon peak and carbon neutrality due to their lightweight and high-strength characteristics.Improving the interfacial bonding strength of composites is a key and challenging issue.This paper addressed the challenges associated with the poor surface wettability and low mechanical property conversion rate of carbon fibers by outlining theories of interface reinforcement in CFRP and methods for surface treatment of carbon fibers,emphasizing oxidation methods,chemical grafting,and coating processes to improve the mechanical properties of composites through physical or chemical means.Furthermore,this article delved into the compatibility between carbon fiber and resin matrix from the respective performance characteristics of thermosetting and thermoplastic resins,and proposed different solutions.Finally,this paper reviewed the research progress of CFRP in the fields of aviation,wind turbine blades,and new energy vehicles,and proposed development suggestions for material research under the background of aircraft lightweighting,wind turbine scaling,and popularization of electric vehicles,such as optimizing specific surface modification technologies for carbon fiber with different surface morphologies such as high strength or high modulus,developing modification methods for different resins,developing carbon fiber sizing agents for different categories and application scenarios,strengthening the research on composite materials interface enhancement theory and interface characterization technology,and formulating a standardization system for carbon fiber composite materials.
