This paper studies the flexural behavior of CFRP/aluminum hybrid laminate (FML-fiber metal laminate) among various temperature environments ranged from 25°C to 150°C through experimental, predicted, and numerical methods. Firstly, a series of three-point bending tests of FMLs (FMLs-A: orthogonal direction 0°/90°, FMLs-B: cross direction 45°/-45°) are conducted, bending load-displacement curves and failure morphologies of FMLs among various temperatures are recorded and compared. Then, considering the discreteness experimental data, the Weibull statistics model with two-parameter is developed to evaluate the ultimate bending strength of FMLs under different temperatures for better engineering application. Finally, the bending numerical models are established to characterize the effect of layer direction on damage modes and progressive damage evolution process of FMLs. The results indicate that the flexural strength of FMLs has a nonlinear downward trend with the increase of temperature. The similar delamination damage under different temperatures can be observed, especially for the higher temperatures. The comprehensive understanding of flexural behavior of FMLs can be beneficial to better design and manufacture the corresponding FML structures among various temperature environments.
