The invention provides a fatigue life prediction method of composite material, an apparatus and electronic equipment thereof, which belong to the fields of material performance prediction and structural design. The method is characterized in that a performance database of a preset angle paving layer unidirectional plate is established, wherein the database comprises fatigue load and fatigue life corresponding to the preset angle paving layer unidirectional plate; a fatigue life curve corresponding to the preset angle paving layer unidirectional plate is constructed according to the performancedatabase; the fatigue life curve of a lamination plate is determined according to the fatigue life curve of the preset angle paving layer unidirectional plate, and the fatigue life of the composite material can be predicted according to the fatigue life curve. The fatigue life prediction method can solve the problems that prediction in the prior art is too conservative, so that the material cannot be fully used, a prediction period is long, and the cost is high.
