Abstract Long glass fiber reinforced polypropylene (LGFPP) is a lightweight, high-strength, and easy-to-recycle new vehicle composite material, and has good mechanical properties, heat resistance and weather resistance. In this work, the effect of ambient temperature on the mechanical properties of LGFPP was studied through tensile tests under different temperature environments and its failure mechanism was analyzed. The results show that the matrix has better encapsulation of the fibers when the ambient temperature is minus 20 ℃, which is conducive to load transmission. The damage is manifested as matrix failure and the fracture surface is relatively flat, and the tensile strength is increased by 18.93% compared with room temperature. As temperature arises, the resin matrix gradually becomes soft, and the interface strength between the resin and the fiber decreases, which is partly manifested as the interface failure between the fiber and the matrix. It reduces the damage of the fiber load, which leads to the decrease of the strength of LGFPP. When the ambient temperature reaches 100 ℃, the tensile strength is 45.84% lower than that at room temperature. The homogenized RVE model of LGFPP was established, and the mechanical response and elastic constants at different temperatures were predicted. The numerical simulation results and theoretical values were in good agreement with the experimental results. It provides guidance for the adaptability of LGFPP in the application environment.
