In order to investigate the tension-tension fatigue life distribution of basalt fiber reinforced polymer (BFRP) composites, 70 specimens were tested at same stress level (70% σ m ). The test results show that BFRP is heterogeneous and its fatigue life data are of great dispersion. In addition, the statistical analysis shows that the fatigue life distribution of BFRP is highly consistent with the Weibull distribution of two parameters if compared with the normal distribution, and the linear correlation test shows that the goodness of fit is 99.23%.
