英文摘要	In order to evaluate the residual strength of wind turbine blade composite materials(that is, fibre reinforced composite materials)under random load, the effect of load randomicity and dispersion of material properties on the probability distribution of residual strength is considered. Firstly, the prediction model of fatigue life for wind turbine blade composite materials under random load is proposed based on the Miner theory and whole probability formula. Then the probabilistic model of residual strength of wind turbine blade composite materials under random loads is derived based on the assumption that the residual strength and residual fatigue life depend on the same damage state in materials. Finally, the effectiveness of the proposed model is verified through the static strength test data and fatigue life test data of wind turbine blade composite laminates (a whole structure composed of multiple single layer plates). The results show that the proposed model can reveal the general degradation law of residual strength of wind turbine blade composite materials, which has an important guiding significance for fatigue life prediction and reliability assessment of wind turbine blade composite materials under random load. © 2018, Editorial Board of Acta Energiae Solaris Sinica.
