摘要

Due to advantages in strength, toughness and lifespan, carbon fiber reinforced plastic (CFRP) has a wide range of applications in load-bearing structures in aircraft and other aerospace and transportation products. However, precise interference-fit technology for the CFRP used in the new generation aircraft brings the conflict between strength and performance, which contains a myriad of challenges for the theoretical understanding and modeling of the technology. This paper analyzes the state of the art of the precise interference-fit technology for aircraft composite structures, as well as the characteristics, difficulties and application status of the technology. The technical system framework of the technology is proposed. Key problems of the technology, including the stress analysis method of the composite material interference hole, the damage initiation and expansion mechanism of the structure, as well as the degradation mechanism of mechanical properties are summarized. Development trends of the technology in terms of damage modeling, fastener design, process planning, and material application are also discussed.
