Abstract
Carbon fiber reinforced polymer (CFRP) composites have found widespread use in various lightweight engineering applications, owing to their high stiffness and strength at low density. Nevertheless, they exhibit certain weaknesses, such as low bearing strength, leading to reduced impact resistance in CFRP components. In addressing this challenge, metal/CFRP composites have emerged as an alternative, leveraging the ductility of metals along with the high specific strength of the CFRP composites. In this study, tensile tests were conducted on the CFRP composite plates with 0°, 90°, and ±45° stacking sequences, and the corresponding load-displacement curves were obtained. The numerical simulation of tensile tests was conducted by the LS-DYNA software, and the numerical model was verified with the experimental results. Furthermore, numerical simulations were conducted to examine the influence of various metal types on the failure behavior of metal alloy/CFRP hybrid composite plates with different thicknesses under tensile loading. The results indicate that both the thickness of the hybrid CFRP composites and the type of metal have a substantial impact on the performance of metal-hybrid components. Additionally, a comparison between the tensile test results and numerical simulation results reveals a good agreement.
