Abstract:

Carbon Fiber-Reinforced Polymer (CFRP) composites, known for their exceptional lightweight and high-strength properties, are increasingly valued in the field of aero-engine applications. However, the interfacial issues between fibers and resin matrix significantly limit the full potential of CFRP composites. This paper provides an in-depth discussion on the research progress, existing challenges, and future trends in three key areas: interfacial mechanical properties of carbon fiber/matrix, interfacial damage mechanisms and simulation methods, and interfacial reinforcement mechanisms and strategies. The research indicates that experimental testing, microstructural characterization, and analytical simulation techniques can effectively reveal the influence of interface on the macroscopic mechanical properties of CFRP composites. Interfacial damage exhibits multiple modes including delamination, debonding, and crack propagation, whose evolution processes are governed by the synergistic effects of mechanical loading, thermo-mechanical coupling, and environmental factors. These damage mechanisms can be effectively characterized through numerical methods such as macroscopic finite element simulation, micro-and meso-mechanical models, and multi-scale simulations. Interfacial modification, nano-reinforcement, and novel resin matrix development strategies have significantly enhanced interfacial adhesion properties, thereby improving the mechanical performance of composites. Nevertheless, the application of CFRP composites in the extreme service environments of aero-engines still faces several challenges: limitations in existing interfacial mechanical property characterization techniques, insufficient research on multi-physics and multi-scale coupled damage mechanisms, and inadequate long-term stability of interfacial reinforcement effects. Addressing these critical issues will provide essential theoretical guidance and technical support for enhancing the service reliability of CFRP composites aero-engines and other high-end equipment applications.
