In this paper, the tensile fatigue performance of CFRP rods used for cable before and after hygrothermal and freeze–thaw cycles is investigated experimentally. The tensile fatigue and residual tensile performances of kiloton CFRP cable are verified after hygrothermal and freeze–thaw cycles. Optical frequency domain reflectometry technology is employed to monitor the stiffness degradation of CFRP cables during fatigue loading. The results indicate that the hygrothermal and freeze–thaw cycles release the residual stress within CFRP rod, which improves the fatigue resistance. By contrast, the hygrothermal and freeze–thaw cycles have no significant effect on stiffness degradation of CFRP rod. The kiloton CFRP cable can withstand 2,000 k cycles of tensile fatigue after hygrothermal and freeze–thaw cycles, and the stiffness degradation of CFRP cable is negligible. The residual tensile bearing capacity of CFRP cable after fatigue is 10,731 kN, corresponding to a residual strength retention rate of 105 %.

Due to complex geometries, directional solidification and sufficient feeding are often not possible, giving rise to solidification defects and shrinkage pores. These microstructural aspects influence the service life, as demonstrated by fatigue tests on automotive engine blocks and cylinder heads. However, understanding the damage process and correlating it with the microstructure is difficult due to the large number of influencing factors and their interdependencies.

Mechanical resonance and ultrasonic fatigue testing in combination with high-resolution microstructure analysis show a reduction in fatigue life with increasing SDAS.
