Effect of stacking sequence of fibre metal laminates with carbon fibre reinforced composites on mechanical attributes: Numerical simulations and experimental validation

Fibre Metal Laminates are structures used primarily in aerospace applications because of their principal advantages such as high strength, lower density, and impact resistance. In the present work, a systematic assessment has been made to evaluate two different stacking sequences FMLs (Type – I (AA 6061/Carbon Fibre/AA 6061), Type II (Carbon Fibre)) against pure carbon composite - III) baseline for improvement. The investigations enhanced resistance, improved tensile increased flexural capability, microstructural evolution, surface composition. Mechanical-based testing resulted that shows significant performance followed by II. maximum values test, ultimate load bearing capacity during test were around 192.92 MPa, 9.3 J, 155 N, respectively. Correlations experimental results drawn numerical simulation validate results. Microstructural evolution indicated good bonding capability FML with fibre. EDX analysis was carried out analyse chemistry. Selected Laminate sequence can help improving aeronautical industry's structural ductile properties together fatigue strength
