“…Various surface preparation routes can be applied to improve the metal/polymer bonding. It can be carried out mechanically by brushing, grit blasting, or grinding to increase the anchorage possibilities [32,33]. Chemical treatments such as electrochemical etching, anodisation, and the addition of adhesive promoters can all be used to improve adhesion [34,35].…”

The demand for innovative materials has been a significant driving force in material development in a variety of industries, including automotive, structural, and biomedical. Even though a tremendous amount of research has already been conducted on metallic, polymeric, and ceramic materials, they all have distinct drawbacks when used as mono-materials. This gave rise to the development of nature-inspired sandwich-structured composite materials. The combination of strong metallic skins with soft polymeric cores provides several advantages over mono-materials in terms of weight, damping, and mechanical property tuning. With this in mind, this review focuses on the various aspects of MPM SMs (Metal/polymer/metal Sandwich Materials). The reasons for the improved qualities of MPM SMs have been discussed, as well as the numerous approaches to producing such SMs. This review shows the various possibilities of achieving such SMs in complicated forms via different shaping techniques and intends to highlight the properties of MPM SMs’ remarkable qualities, the current trend in this field, and their potential to meet the demands of many industries.

“…Fibre-reinforced laminates as well as hybrid multilayer compounds were manufactured in a Collin Press Type P 300 P. These were subjected to a surface modification before consolidation. The mechanical surface treatment proved appropriate due to its positive effects on the surface roughness, surface structure and the additional removal of surface contamination [13,17]. The tool with an effective press area of 260 x 260 mm² was mutually heated by heating cartridges.…”

For several years, thermoplastic hybrid laminates form a new class in the field of material compounds. These laminates consist of fibre-reinforced plastic prepregs and metal layers in alternating order. Compared to conventional thermosetting multilayer composites, these laminates are suitable for large-scale production and can be manufactured with significantly reduced cycle times in the thermoforming process. In the framework of this contribution, the influence of the cooling rate of carbon fibre-reinforced thermoplastic composites and hybrid laminates was investigated with regard to crystallinity and the resulting mechanical properties. Polyamide 6 and thermoplastic polyurethane as matrix systems were examined, in particular.Additionally, the differential scanning calorimetry was used in order to investigate the influence of the cooling rate on the crystallisation behaviour. It could be determined that the cooling rate has a limited influence on the crystallisation of polyamide 6 and this influences the mechanical properties. Furthermore, a reliance of process parameters on the characteristics profile of composite materials and material compounds with thermoplastic polyurethane could be identified. Depending on process conditions, tensile, bending, and interlaminar shear properties fluctuate up to 20 % in fibre-reinforced laminates and up to 32 % in hybrid laminates. Moderate to fast cooling rates result in optimum mechanical characteristics of tensile properties in fibre-plastic-compounds. Fast to very fast cooling rates are advisable for bending and interlaminar shear properties. Highest tensile and bending characteristics are achieved in hybrid laminates by using fast to very fast cooling rates, while interlaminar shear properties tend to be highest in slow to moderate cooling rates.

[4][5][6] Recently, lab-scale thermoplastic FML parts such as TiGr, 7 CAPAAL, 8 and CAPET 9 have shown their excellent tensile strength, flexural strength and inter-laminar shear strength.…”

Spring‐back is a forming defect in thermoplastic fiber‐metal‐laminate (FML) structures that is influenced by all steps of the forming process. Here, we propose a complete CAE chain to predict spring‐back in a FML parts during one‐step hot stamping by fully considering the material properties, latent heat, thermal mismatch, and modulus mismatch during forming and cooling. Then, constitutive models of the aluminum sheet, a visco‐hyperelastic constitutive model, and an elastic model of the UD CF/PEEK prepregs during hot‐stamping and cooling are introduced to describe the deformation behavior. A Coulombic friction model, latent heat model, and contact resistance model are also proposed to describe the interfacial flow, heat generation, and thermal conductivity. The proposed models and CAE chain are validated by the experimentally determined punching force, geometric shape, temperature, and spring‐back angle. The S‐shaped feature of the FML greatly increases the spring‐back of the FML specimens, and lower punching speeds and higher forming temperatures decreases the S‐shaped feature, thereby reducing the spring‐back angle.Highlights A complete CAE chain was proposed to predict spring‐back in a FML curved beam. A new visco‐hyperelastic constitutive model of the CF/PEEK was applied. The latent heat and thermal mismatch were considered in cooling simulation. The S‐shaped feature of the FML greatly increases the spring‐back. The thermal mismatch increased the S‐shaped feature of the FML.
