【Abstract】 The tensile mechanical properties were the basic mechanical properties of composite laminates. The study of the influence of humid and hot environment on the tensile mechanical properties of glass fiber composite could provide an important reference for the engineering application of composite materials. The tensile mechanical properties of AC318/S6 C10-800 composites under different hygrothermal environments were studied,and the influence of environment on the elastic modulus and tensile strength of AC318/S6 C10-800 composite was analyzed. The results show that the strength data of dry condition at low temperature is slightly higher than that at room temperature,and the strength data of wet condition at 70 ℃ is the lowest. With the increase of test temperature,the 0° tensile strength and 90° tensile strength could decrease linearly. The results provide reference for the engineering application of AC318/S6 C10-800 composites.更多还原
