Abstract

Adhesive structures can provide connection strength without damaging the material and are important for connecting heterogeneous materials. This paper investigates the effects of different bonding parameters and hygrothermal environments on the mechanical properties and failure modes of CFRP-Al adhesively bonded structures. The results of the experiment indicate that the water absorption rate is directly proportional to the temperature of the water bath. Additionally, the ultimate tensile load of the samples decreased by 8.99 %, 22.58 %, and 42.97 % after being subjected to water baths at 25 °C, 50 °C, and 80 °C, respectively. This paper predicts the mechanical properties of CFRP-Al adhesive structures in hygrothermal environments using UMAT and USDFLD subroutines in ABAQUS finite element software. The accuracy of the simulation model is verified through comparison with experiments. On this basis, the effects of various bonding parameters (bonding length, thickness, width, and lay-up angle) on the mechanical properties and failure modes of CFRP-Al adhesively bonded structures in hygrothermal environments are studied, providing valuable insights for the design of dissimilar material joining techniques in complex environments.
