“…It can be observed that the expansion domain is much more extended. Reyes et al [4] have reported results on Aluminium 2024 alloys concerning the decimetric flat punch that are similar to the ones obtained here. The huge difference between centimetric and decimetric flat punch (figure 5) may be due to two main causes: On the centimetric test, defects have more impacts due to their relative size (towards the sample dimensions) which prevent strain to reach a high maximal level (0.2 for the decimetric punch).…”

“…This diagram generally corresponds to the boundary between uniform strain and diffuse necking [1][2][3] but the choice of the limit criteria remains an open question. Data related to Forming Limit Diagram (FLD) of 2024 Al alloy have been reported in the literature (see for instance [4]). Ghosh et al [5] and Shu et al [6] have underlined that the maximal strains are depending on the punch geometry.…”

The effects of punch geometry and sample size on forming limit diagrams in expansion are investigated in the case of a 2024 aluminium alloy. Four configurations were selected: flat punch (Marciniak test) or hemispheric punch and decimetric vs. centimetric tooling dimensions. Both decimetric and centimetric deep-drawing devices are associated with an image correlation tool that allows to identify without any contact the deformation on the surface of planar or non-planar specimens. Strains on the surface of the samples are observed by means of a double numerisation in three dimensions of the sample before and after deformation by using stereoscopic vision and triangulation. Finally, deep-drawing limit of the four configurations are compared in expansion state and with literature. Results mainly show that hemispherical punch is less sensitive to size effect than Marciniak test.

“…In comparison, FMLs made from thermoplastic-based composites offer improved toughness and have the potential advantage in manufacturing of requiring short process cycle times. These novel thermoplastic fibre-metal laminates can lead to a rapid and low-cost production of lightweight structural components (Reyes and Kang, 2007). Increasing environmental concerns have encouraged researchers to develop ranges of recyclable composites based on natural fibres such as jute, kenaf, coir, sisal (Rao et al, 2010;Yusoff, Takagi and Nakagaito, 2016).…”

ABSTRACTFibre metal laminates (FMLs) have been widely used to manufacture airframe components. This work describes novel sisal fibre reinforced aluminium laminates (SiRALs) that have been prepared by cold pressing techniques and tested under tensile, flexural and impact loading. The pristine sisal fabric and the sisal fibre reinforced composites (SFRCs) were also tested to understand the difference in mechanical performance of the sisal fibre metal laminates. The SiRALs achieved not only the highest modulus and strength, but also the highest specific properties. The mean specific tensile strength and modulus of the SIRALs reached increases of 132% and 267%, respectively, when compared to the sisal fibre reinforced composites (SFRCs). Moreover, the mean specific flexural strength and modulus of the SiRALs were significantly higher than SFRCs, revealing increases of 430% and 973%, respectively. A delamination fracture mode was noted for SiRALs under bending testing. The SiRALs can be considered promising and sustainable composite materials for structural and multifunctional applications.

“…Gresham et al [16] studied deep drawing of aluminum/ polypropylene-based FMLs, and they found fracture of aluminum layers at low forming temperature and wrinkling defects at high temperature. Reyes et al [17] studied delamination between the composite and aluminum layers in the stretch forming of polypropylene/glass fiber/aluminum FMLs, and Mosse et al [18] analyzed the effects of forming temperature and speed on the delamination of these FMLs. They suggested a forming temperature with a window (range) of 15°C to avoid delamination.…”

Semi-crystalline thermoplastic-based composite laminates and fiber metal laminates have a narrow forming temperature window, which limits formability of these products. The intention of this study was investigation of nonmelting amorphous polyvinyl chloride as a proper matrix to increase the formability and forming temperature window of these products. For this, [45/−45] and [0/90] layups of polyvinyl chloride-based composite laminates and fiber metal laminates were produced using the film-stacking procedure and later press formed into channel sections at six temperatures in the range of 80 to 200°C. The effects of the layups and forming temperatures on the forming loads and spring back of the formed profiles were measured, and their effects on the fiber buckling, wrinkling, and delamination of the profiles were evaluated using optical microscope images. The effects of layups and forming temperatures on the deformation mechanisms were also analyzed using the grid strain analysis method. Of the fiber metal laminates, 160°C was found as the minimum forming temperature, and for the composite laminates, 120 and 160°C were found as the minimum proper forming temperatures of [45/−45] and [0/90] layups, respectively. Finally, the forming temperature windows and formability of polyvinyl chloride matrix composite laminates and fiber metal laminates were found higher than semi-crystalline matrices.
