摘要

Ultra-high cycle fatigue problem has received more and more attention with the continuous improvement of the reliability and life index of modern equipment, and has become a hot spot in fatigue research. As the non-metallic material with the most application potential in the modern aviation industry, the ultra-high cycle fatigue problem of carbon fiber reinforced plastic (CFRP) is the most prominent. In this paper, the research progress of ultra-high cycle fatigue research of CFRP has been systematically sorted out and summarized from three dimensions of test method, fatigue fracture macro-micro characteristics and fatigue damage model construction, including the adopted technical methods, the mechanism of fatigue crack initiation, the characteristics of S-N curve, Goodman diagram and the influence of humidity and other influence factors. The mechanism, evolution and model of CFRP ultra-high cycle fatigue damage are expounded, and the problems existing in the ultra-high cycle fatigue research of CFRP are presented.
