Comparison of stacking sequence on the low‐velocity impact failure mechanisms and energy dissipation characteristics of <scp>CFRP</scp>/Al hybrid laminates

Abstract Compared with the resin‐based composite laminates, fiber metal laminates (FMLs) have superior impact resistance. In this study, investigations were made to reveal effects of stacking sequence on low‐velocity failure mechanisms and energy dissipation characteristics carbon reinforced plastics (CFRP)/Al hybrid same areal density. Experiments carried out characterize typical mechanical responses. Failure morphologies evaluated by X‐ray computed tomography scanning techniques. Then numerical simulations based three‐dimensional progressive damage analysis applied dynamic evolution process characteristics. Results indicated that plastic deformation aluminum layers acted as dominant factor in dissipation. Stacking exterior surface could increase absorbed reduce fracture behavior component layers. The specimens more CFRP stacked exhibited severe larger delamination areas, thus promoting dissipated cracking delamination. This work intended provide practical guidance for structural design polymer/metal protective structures.
