Fibre metal laminates, hybrid composite materials built up from interlaced layers of thin metals and fibre reinforced adhesives, are future-proof materials used in the production of passenger aircraft, yachts, sailplanes, racing cars, and sports equipment. The most commercially available fibre–metal laminates are carbon reinforced aluminium laminates, aramid reinforced aluminium laminates, and glass reinforced aluminium laminates. This review emphasises the developing technologies for forming hybrid metal–polymer composites (HMPC). New advances and future possibilities in the forming technology for this group of materials is discussed. A brief classification of the currently available types of FMLs and details of their methods of fabrication are also presented. Particular emphasis was placed on the methods of shaping FMLs using plastic working techniques, i.e., incremental sheet forming, shot peening forming, press brake bending, electro-magnetic forming, hydroforming, and stamping. Current progress and the future directions of research on HMPCs are summarised and presented.

“…The material undergoes shearing and is subjected to cutting action at the peripheral and axial teeth. The distribution of cutting between the two teeth significantly lowers the magnitude of the cutting forces [16,17]. The reduced work-tool contact lowers the cutting temperatures during helical milling [16,17].…”

“…The distribution of cutting between the two teeth significantly lowers the magnitude of the cutting forces [16,17]. The reduced work-tool contact lowers the cutting temperatures during helical milling [16,17]. The reduction in the magnitude of cutting forces and temperature, along with the improved chip breakability, helps to lower the surface roughness of the helically milled bores [17,18].…”

“…Aluminium alloys are the basic material for the production of Fibre Metal Laminates (FMLs) for the aviation industry: glass-reinforced aluminium laminates (GLARE), aramid-reinforced aluminium laminate (ARALL), carbon-reinforced aluminium laminate (CARALL), kenaf fibre-reinforced aluminium alloy (CAKRALL) and flax fibre-reinforced aluminium alloy (CAFRALL) [5]. In addition to the above-mentioned groups of laminates, aluminium alloys are used in various configurations to produce other layered composites based on, e.g., EN AW-2024 [6], EN AW-5083 [7], EN AW-6082 [8], EN AW-7075 [9], EN AW-8090 [10] and many other aluminium alloys [5].…”

Assessment of the Tribological Properties of the Steel/Polymer/Steel Sandwich Material LITECOR

The article presents the results of tribological investigations into the steel/polymer/steel sandwich material LITECOR® developed by ThyssenKrupp Steel Europe for applications in the automotive industry. Friction tests were carried out by means of a strip drawing test with the use of a special tribotester mounted on a uniaxial tensile test machine. The influence of sheet deformation on the value of the coefficient of friction (COF) was considered. For this purpose, the samples were subjected to a pre-deformation of 4%, 8% and 12%. Friction tests were carried out with different force values and under different friction conditions, i.e., in dry friction conditions and lubrication of the sheet surface with L-AN 46 machine oil. The highest values of COF were observed for as-received sheets. In contrast, apart from the friction process under the conditions of the lowest force analysed, the lowest value of the COF was observed for pre-strained sheets with a deformation of 12%. The lubrication efficiency of the pre-strained strip specimens with ε = 4% was between 10.5% and 16.3%, with a trend of increasing lubrication efficiency with increasing force. For pre-strained sheets with deformation ε = 12%, there was a trend of decreasing effectiveness from 14.9% to 9.03% with an increase in force.
