A Numerical Investigation into the Crashworthiness of Bio-Inspired Aluminum/CFRP Tubes Under Lateral Loading

This study explores the energy absorption characteristics of bio-inspired aluminum/carbon-fiber-reinforced polymer (Al/CFRP) hybrid tubes under quasi-static lateral loading. Using cohesive zone models (CZM) for adhesives and advanced damage models for composites, numerical simulations were performed on configurations with varying ply angles ([۰/۹۰], [۹۰/۰]) and layers (۲, ۴, and ۸). Results highlight that ۴-layer [۰/۹۰] configurations achieve the best balance between energy absorption and structural integrity, outperforming both aluminum-only and other hybrid designs. The findings underline the efficacy of adhesive bonding in enhancing crashworthiness, making such hybrid structures promising for energy-absorbing applications.
