Interlaminar Shear Strength Behavior of Carbon Fiber Reinforced Aluminum Alloy Laminate

The interlayer bonding ability is a crucial indicator of thermoplastic fiber metal laminates (FMLs). Using different preparation strategies and adhesive thicknesses, a series of fiber metal laminates were prepared from 2024-T3 Al alloy, unidirectional carbon fiber prepreg tapes, and films of polyeth...

Description
Summary:The interlayer bonding ability is a crucial indicator of thermoplastic fiber metal laminates (FMLs). Using different preparation strategies and adhesive thicknesses, a series of fiber metal laminates were prepared from 2024-T3 Al alloy, unidirectional carbon fiber prepreg tapes, and films of polyether ether ketone. The span-thickness ratio for this type of laminates was examined and characterized to identify the most suitable span-thickness ratio. The effects of adhesive layer thickness on the interlaminar properties of FMLs were investigated, and the failure processes were analyzed by microscopic observation. The results show that lower span-thickness ratios have better applicability in thermoplastic carbon fiber aluminum alloy laminates. The adhesive layer presence significantly affects interlaminar properties independent of its thickness, and the FMLs with unidirectional alignment and anodized treatment possess stronger shear resistance.
