Abstract: Structural integrity is the primary factors determining the safety and lifespan of aeronautical structures and pose signifi-cant challenges to the application of novel materials, structures, and techniques in the field of aviation. Clarifying and enhancing the structural integrity performance of advanced materials and structures can facilitate the utilization of the outstanding capabilities in aviation structures, thereby achieving more reliable, efficient, and economical aviation struc-tural goals. The present paper systematically reviews the main achievements and recent work conducted by member countries of the International Committee on Aeronautical Fatigue and Structural Integrity (ICAF) in the past two years in this field. This paper also focuses on introducing the recent advancements made by scholars from various fields in terms of the fatigue life of advanced materials, structures, and techniques, aiming to stimulate continuous attention of researchers in aeronautical structural field towards the progress and issues about the aviation structural integrity. Build-ing upon this foundation, combined with the extensive progress made in material, structural, and techniques domains in recent years, along with emerging demands for aeronautical structural performance, this paper also presents sugges-tions and prospects for the fatigue research of novel materials, structures, and techniques, as well as the design of future aeronautical structures, in order to further promote the development of this field.

Key words: aeronautical structures, advanced materials, advanced techniques, structure integrity
