Abstract

The evolution of automobiles necessitates a balance between weight reduction and enhanced safety. Leveraging the hot stamping technique for manufacturing aluminum alloy and carbon fiber-reinforced polymer (CFRP) composites laminate offers significant potential in the automotive sector due to their advantageous qualities of high strength, low density, and cost-effective processing. This study employs hot stamping to integrate aluminum alloy sheets with CFRP prepreg, yielding aluminum alloy/carbon fiber laminated panels. The research investigates the impact of aluminum alloy surface treatment, consolidation dwell time, consolidation pressure during thermal-hot stamping, and CFRP surface modifications on the adhesive bond strength of hybrid aluminum alloy/CFRP components using delamination experiments. By combining an internally cohesive force model based on fracture toughness energy and the Hashin progressive failure criterion, a finite element model is developed to analyze failure modes in multi-material joints during delamination. Findings indicate that noticeable failure in both aluminum alloy and CFRP did not manifest during delamination. Instead, damage emerged within the resin matrix of k.the bonded area due to tensile stress, accompanied by cohesive damage within the joint. Initial adhesive damage appeared at the boundaries of the bonded region, gradually extending from the periphery towards the central bonding area. The experimental results are verified.
