Composite materials are widely used due to their excellent mechanical properties,and complex application conditions will directly or indirectly affect the strength and service life of composite structures.In this paper,based on ASTM standards,the tensile strength and failure behavior of an EH107 composite material are compared and analyzed under five environments:room temperature(23℃)dry,82℃ dry,82℃ wet,130℃ dry and 130℃ wet.The results show that compared with the open-hole tensile strength of room temperature dry,the open-hole tensile strength of 82℃ dry is increased by 1.78％,the open-hole tensile strength of 82℃ wet is increased by 3.07％,the open-hole tensile strength of 130℃ dry is increased by 3.15％,and the open-hole tensile strength of 130℃ wet is increased by 7.22％.
