Abstract: Temperature influence tests were carried out for the commonly used mechanical properties parameters of the new IMA/M21X composites, and the tensile tests at room temperature, 70 ℃, 120 ℃, 150 ℃, and 180 ℃ were carried out for the 0° and 90° ply test specimens, as well as the measurements of the shear modulus G12,G13, and G23 at corresponding temperature conditions. The results show that the transverse modulus of elasticity is greatly affected by temperature, decreasing by 34.78% from room temperature to 180 ℃. TransversePoisson’s ratio approaches 0 and increases with increasingtemperature. The shear modulus decreases with increasing temperature, unlike the usual assumption that G12=G13, at room temperature, the material G12 is 28.49% larger than G13. The tensile modulus and in-plane shear modulus of IMA/M21X material are relatively superior, but the inter layer shear modulus is relatively weak. The mechanical parameters of IMA/M21X at room temperature and temperature were obtained, and the effect of temperature on the properties of IMA/M21X was investigated.
