The research involved selecting different carbon/glass hybrid ratios (2:6, 4:4, 6:2) as blade reinforcement materials. Both finite element simulation and experimental testing were combined to analyze the effects of service temperature and carbon-glass hybrid layer ratio on the static characteristics of composite wind turbine blade samples.Furthermore, the study simulated the impacts of extreme operating conditions on the strength characteristics of carbon-glass hybrid composite wind turbine blades at wind speeds of 12m/s, 22m/s, and 30m/s,respectively.Subsequently, an analysis was conducted to determine the effects of temperature and wind speed on the fatigue life of composite blades with a carbon-glass hybrid layer ratio of 6:2. The findings indicate that the elastic modulus and tensile strength decrease with increasing temperature, with the tensile strength of the 6:2 carbon-glass hybrid composite fiber reinforced wind turbine blade peaking at 45℃, 25℃, and − 35℃. Specifically, at these temperatures, the tensile strength was 44.7%, 41.5%, and 33.5% higher than that of glass fiber composites under equivalent working conditions.Notably, extreme operating conditions caused the fatigue life of carbon-glass hybrid composite wind turbine blades to deviate from the rated operating conditions by 92.6%,with the − 35℃ environment resulting in a deviation of 97.8% from the rated operating conditions. wind turbin blade carbon/glass hybrid equivalent stress extreme working conditions Full Text Additional Declarations No competing interests reported.
