In the current work, fiber‐metal laminates (FMLs) consisting of alternated continuous fiber‐reinforced thermoplastic composite layers and aluminum alloy sheets were proposed by the hot‐pressing method. Carbon fiber‐reinforced polyamide 6 (PA6/CF) and glass fiber‐reinforced polypropylene (PP/GF) prepregs were selected as composite layers. The effect of the assembly method between composite prepreg and aluminum sheets as well as the stacking configurations on the flexural response of FMLs were investigated. Meanwhile, the macro and micro‐structural observations were performed to characterize failure mechanisms in these structures. Experimental results revealed that the strength and stiffness of hybrid FLMs depended on the material property on the surface layer. With the stacking sequence of aluminum sandwiched by PA6/CF achieved the highest flexural strength of 535.3 MPa and modulus of 63.6 GPa in the series of FMLs, which could achieve satisfied lightweight and strength‐stiffness properties. The ductile deformation of aluminum sheets and fracturing and pulling out of the fibers were the main characterized failure mechanisms of thermoplastic FMLs. For glass fiber‐metal laminates, stacking configurations of three aluminum sheets alternation with four PP/GF intermediate layers achieved a favorable flexural property. Above all, the proposed thermoplastic FMLs have great potential in civil applications especially in the automobile industry as structural parts.Highlights Thermoplastic fiber‐metal laminates are designed and fabricated. The assembly method and stacking sequences influence the flexural property. FMLs with PA6/CF and aluminum achieve satisfied strength stiffness. PP/GF prepreg and aluminum layer display ductile deformation mode.

“…In recent years, metal-CFRTP components show broad application prospects in locomotive industry, such as automobile chassis and high-speed railway safety seats. [5][6][7] For the bonding of metal/CFRTP, adhesion bonding or mechanical fastening is commonly employed. Nevertheless, both methods have intrinsic defects such as long processing cycle, unfriendly environment, increased weight, fiber interruption and stress concentration.…”

Metal‐polymer hybrid joints can contribute to weight reduction and have potential use in transportation industries. In this work, laser texturing was used to enhance bonding strength of laser‐welded 304 stainless steel/carbon fiber reinforced thermoplastics (CFRTP) joint. The tight relationship between surface texture spacing and porosity characteristic as well as tensile property of joint was systematically investigated. The temperature field distribution during welding process was simulated and the mechanism of porosity suppression depending on grid spacing was discussed. The result showed that the number of pores at cross‐section decreased first and then rose with the increase of micro‐structure spacing, which corresponded to the variation trend of bonding strength and was inconsistent with the evolution of connecting area. The joint achieved the minimum porosity defect and reached maximum fracture load of 2594 N when the grid spacing was 1.2 mm, while the maximum joint width of 9.28 mm was obtained when 0.4 mm spacing was adopted, indicating that the joint quality rather than mechanical interlocking governed the mechanical property of joint. Appropriate interface contact conductance (TCC) related to texture spacing could optimize the interface heat dissipation rate, and was the key factor to efficiently control the shrinkage porosity. The TCC of small or large grid spacing was too high or too small, resulting in failure of the heat transfer path through the interface to metal during cooling process. Moreover, the proper texture spacing improved the uniformity of joint strain distribution in tensile‐shear testing, which benefited joint strength.Highlights Laser‐textured grid pattern spacing affected number and distribution of pores. Heat dissipation rate varied with various spacing at joint interface. 1.2 mm spacing texture reduced stress concentration during tensile process.
