A refined method for determining the basis values of tensile failure strain for ZT7H/5429 composite laminates in hygrothermal environment was proposed. Through the tension tests of the composite laminates with open hole under different environmental conditions, the influence of temperature and humidity on the tensile failure strain was quantitatively analyzed, and a tensile failure strain prediction model was established based on small sample holistic inference technology. The results showed that the tensile failure strain decreased with the increase of temperature, and the decline became flat gradually, while the influence of humidity was not so significant. Based on the tensile failure strain prediction surface, the B-basis value of tensile failure strain was further determined by introducing one-sided tolerance-limit factor. Compared with the traditional single-point method of only analyzing the test results in the single state, the proposed method fully took into account the connection between the experimental data in different states and the B-basis values increased by 2% to 25% in most cases, providing a theoretical basis for the refined design of composite structures.
